I think I get what Sanguinate does but it seems a little niche imo. Not that it's bad, Outcast is a lot like that but then Prince Tenris Mirkblood doesn't make much sense... I think Blood Elemental should say 'this turn' or cost more, as it stands it's pretty much 0 mana. I'm also worried that your class has extremely good curving abilities. I don't remember exactly your basic set but iirc you had aa solid 1-drop in there and adding both Swamp Snatcher and Blood Elemental with Blood Boil as an early finisher sounds really strong. Crimson Tides is really good, I would knock the base effect down to 4 damage. Blood Orb can become really problematic with buffs (Taunt in particular) but maybe I'm too harsh.

I really like your cards ! I'm sorry that I don't really remember your basic set but if you have a flex spot I think your class could use one more weapon generation. I like your Taunt sub-theme but again you have more payoffs than setups. A middle-most buff card could be cool if you don't already have one.

I like your keyword but the cards you use it on aren't balanced at all. Just in Time! is a better Arcane Shot, Mecha-Rex is a better War Golem and Chrommie is a better Vilespine Slayer. I think you should balance each half of the card to be equivalent to a neutral option as the flexibility is really powerful. I also think all Warp effects should be higher cost. First, it would be less confusing if the cost on the mana symbol was in fact the minimum cost for the card, second, it would make it clearer what the keyword does. Initial Raider is a fine card but I'm not really sure you intend its insane synergy with Mecha'thun... The second Arcane Warden seems like a good fit in this set and it's a cool design. It throws me off that the wording order changes for no reason between the basic hero power and the upgraded one...

I would reword Encore as 'a bonus if you have already played a card with the same name this game'. It changes the mechanic a little bit but in a good way because now the opponent can see these effects coming. This change also removes the possibility of a starting hand with both cards negating the cost of Encore. As suggested by someone else, I would change the name to something like 'Second Round' to fit more with your class' flavor. Other than that, I like your set. Maybe Carnival Night is a little crazy with other aggro tools...

I'm going to be very blunt on your hero power question: I don't like hero powers that add cards to your hand. I especially hate it when you have to pay 2 mana to then spend another 1 or 2 mana getting the full value. So yeah I would advise against Vermintide. Verminous Valor is interesting but it can end up useless in a lot of situations. To combat that, I would make a lot of 1 or even 0 mana minions to allow the class to capitalize on it more often. You have a lot of token generators so that should work.

Not much to say about your cards, except Artillery Support is really similar to Starfire so I think you should either make it a cheap version (maybe 3 mana deal 2) or an expansive version (maybe 8 mana deal 8) to differentiate. Warp Lightning is also a little weird since you don't have that many cheap cards.

From your basic set, I get the impression of a slow mid-range playstyle rather than an aggressive swarm. Hopefully, that's what you're going for but then the flavor is a little off.

I'm not a fan of your hero power. Not only is it essentially a 3 mana hero power, but you also have almost no specific synergy (hand size, hand buff, on play effect, etc...) to justify it. I've tried many variations on a minion summoning hero power and it's really hard because Paladin and Shaman have it pretty much covered. Two solutions I would advise are 2 mana "At the start of your next turn, summon a 2/2 Familiar" or "Summon a 2/2 Familiar. You can only have one." if you want to keep this effect. If the card generation is the important part, then make it a 0 mana token or a 1 mana hero power with a 1 mana token to keep the balance in line with other hero powers.

Your cards are pretty cool but Curse of Youth is straight-up Subdue, Dual Potion is a cheaper Drain Soul and Mastering the Basics is a worse The Forest's Aid so I would either scrap them or add more variation.

I like your Rockscale Cod and Zangar Trout but Slitherin Mackarei seems out of place in a class that has just one damage spell. Maybe give it Stealth or Divine Shield ? I like that you only have 3 options rather than the 4 of Shaman but I'm a little on the fence with your hero power costing 2 for no immediate effect. Maybe you could make it 1 mana and bring down all fishes to 1/1s ?

I like you new cards but I wish Fishing Rookie would pull a fish from your deck instead of thin air since you have a lot of synergy with that. Speaking of, this new batch has 3 new tokens in it, on top of the ones from the hero power. That feels like a lot so maybe consider moving some of these cards to later sets. Finally, it's more nitpicky but isn't it weird that a Koi Carp is bigger than a Muskie ? Almost as big a Calve ? Idk the flavor is a bit off on some of these numbers I feel.

Man, I really don't love these hero powers that add a card to your hand. You should try to have all basic Sub-Weapons cost the same (0 in my opinion, or 1 mana hero power and 1 mana spells) for predictability. I like that they are all some sort of removal but I think it's a shame that the Dagger is obviously worse than the others. It creates a lot of "feels-bad" RNG. I would go with something like "Deal 1 damage" (Dagger), "Deal 1 damage to a minion twice" (Holy Water) and "Deal 1 damage to all minions" (Axe). That would put your hero power on the strong side but not quite broken in my opinion. You should also consider adding Spell Damage synergy, otherwise, what's the point ?

Hunter's Whip is a straight-up worse Light's Justice and I know that's your intention but I don't think it's a great idea. Not only is it really boring, it requires synergy to be worth it. Which brings me to Leatherworker... This card text is busted, I'm not sure you can write a stat line that would make it fair. Weapon buffs are weird because most things are linear in Hearthstone (minion Attack, spell damage, healing, etc...) but weapons are multiplicative. The total damage you get is (Attack x Durability) and that can get really out of hand when you increase both at the same time. It also makes games really coin-flippy: if you play a weapon on 1 or 2 and a Leatherworker on 3, you basically snowball out of control and win on the spot ; if you miss one of the two pieces your deck is built around, your whole gameplan walls apart. Not much you or your opponent can do about it either. I would advise you to make Leatherworker buff only Attack or Durability. I also think you should be very careful with balance when it comes to weapons because they can easily slip to one slide into OP territory.

Flick of the Wrist needs more weapons to function. I'm not even sure this effect can work in a class that doesn't generate weapons with it's hero power.

Sidenote : How does a leatherworker improve your weapons ? Maybe that's a reference to the game you're basing this off of...

Right out the gate, I'm a little thrown off by the fact that so many tokens called "skeleton" that are actually different things. I'm also not sure of how applicable your hero power is. You do have a lot of synergy for it, which is good, but idk.

Splintering Shard looks like a worse Umberwing in my opinion. Maybe bump it up to three skeletons so it's a little more varied ? Bone Armor also looks really weak. Either reduce the cost of up the damage. Otherwise, I find your set really solid and it does fell like a basic set. Maybe that's why I'm not super hyped by it but honestly staying simple is a great strength and should be encouraged in a basic set. Well done !

Cool hero power but the Hero Power part should have its own line. The thing I find a little problematic is that the wording means using Through Space but not Through Time in a turn means you're stuck with only 1 hero power trigger the next turn. The flavor is also a little lacking. Why does Space damage the enemy hero ? Why does Time restore Health ?

Your cards are interesting but I think you shouldn't shove so many hero power synergies right away because they require more lines to explain and you and up with to many cards at 3 or 4 lines for the basic set. Also Rewind I don't understand. Does it go back to the first or second hero power ? One is "Through space" and the other "And Time" but Rewind says "Through Time"... 

Your hero power is interesting (well done, I'm not a fan of card generating hero powers) and looks really powerful. Stoneclaw Totem is arguably the best result for Shaman's hero power and yours is really consistent, with a lot of specific synergy on top. Maybe you could make the Apprentices 0 mana 0/1s ?

I'm wondering if Self Defense Training triggers twice on minions that both cost 0 and have 0 Attack. I'm also unsure of what you plan to do with revealed cards. Hand information isn't that valuable and revealing cards is actually an upside for your class so keep that in mind when you balance such cards. Finally, I'm too aware of Freeze Mage to not warn you about the balance of Arcane Sidekick. Spell Damage is usually balanced as worth 1 stat point BUT it's gated behind mana cost with a 2 mana for 1 Spell Damage ratio. The idea is that Spell Damage can stack and get out of hand if it's not properly costed. Cheap Spell Damage is especially problematic because you can combine it with a lot of spells. New cards push these boundaries but for a basic set, I would advise rebalancing this one to cost 2 or change the keyword.

For your showcase cards, I think Orc apprentice is great but Bonus Payment covers themes the former already covers and Arcane Sidekick isn't really representative of the class since it's your only Elemental and you don't have that many damaging spells. I would include Self Defense Training and Magnifying Glass.

Dredger Servant seems really strong, especially with your hero power on 2. Think back to Small-Time Buccaneer. I would drop it to 1 Health to make it fairer. Crimson Knight is really a better Bloodworm, which is fine in terms of balance but quite boring, I would change the stats up a bit. Same thing for Infuse and Lightforged Blessing. Nice rework on Sun Blast !

Your hero power is kinda weird but it can work out with the right synergies. Your cards seem great but most of them are too complicated. I would advise moving some of the four-liners to the initiate set or simplifying their design. Venthyr Assassin could easily read "Poisonous. Battlecry: Deal 1 damage." In Eternal Atonement, going from "Change" to "Set" should bring it down to 3 lines. Maybe only keep the debuff effect for Sinful Brand ? Overall, I like your set.

Your hero power is interesting but it might put a little too much stress on the hero's health. Make sure to include good healing options in your class. You should also word it in a way that makes it cear hero Attack goes away at the end of the turn.

I would put Crimon Sacrifice's effect on a minion and bump up the cost to at least 8, otherwise it's going to be a huge problem. Bloodwalker is a little unclear, I would word it as "This minions loses Attack before it loses Health". Crimson Blast is a cool design but I would tie it to burn because that's just too easy to abuse.

Hard to evaluate anything without much information on the class but I'd say you need to be careful with permanent Attack (capital A) debuffs as they can often be synonymous with completely removing a minion from the field. I would just remove the Silence and go with a more straight forward effect.

Your hero power is nice and simple but I think you need a little more if you plan on adding a ton of synergy for it. For one thing, I'm not a fan of class that utilize both Armor and healing as the two pretty much contradict each other. I also think that hero power refresh synergy works much better with a 1 mana hp or one that have flexible effects. I might go with 1 mana "Restore 1 Health" or "Gain 1 Armor" tho I find the later a little rigid.

I'm gonna assume that Submerged is based on LoR's Depth. While adapting ideas from another card game into Hearthstone is pretty cool, I'd like to remind you that LoR has 40 cards decks when Hearthstone has 30 so I would adapt the number of cards below which Submerged is triggered (probably to 10). Also, I gotta say that this looks a lot similar to the Seawitch concept that won a competition not long ago. I would advise you look into it to make sure you aren't stepping on too many toes, and even consider reflavoring your class.

Your hp synergy cards look great but as it stands the archetype is a little one-dimensional for the reasons I outlined above.

Armor synergy is interesting and something that we don't see much of in Hearthstone. That said, you still have a lot of mechanical conflict with the hero power's healing.

Giant sea monsters are cool but Couatl Goliath's drawback is far too easy to ignore. That makes it a super powerful tempo play for any Aggro or Mid-Range deck.

Right out the gate, I would like to say that, while cheating mana is a fun concept, it can be easy to overdo it. Just something to keep in mind in the future.

Some of your cards seem to be on the complex side so I would advise moving more convoluted ideas for the Initiate set. Also consider adding Mech synergy as you seem to have a lot of those.

I like you concepts a lot ! I think you should push it a bit with weapon buffs, especially beyond just stat increases.

I'd like to see what your class can do beyond weapon synergy tho. I would assume that it leans on the control side based on what's available right now but you could go a more aggressive direction.

Nice hero power ! Maybe you could rebrand this as a gambler ? Magician sounds really similar to Mage...

Your cards look great but there are spaces in weird places... Maybe this is a formating issue. Either way, I'd like to see more of your class !

Nice flavor you got there ! It's cool to see a less serious concept for once :)

Your hero power is interesting but the variance on it is quite problematic. Sometimes it's a literal waste of 2 mana, sometimes you'll draw 5 fishes in a raw and overwhelm your opponent. I would either have the fishes go to your hand or to the top of your deck to mitigate that. I'm also not a fan of the Shaman-esque design but I think you're close to something great. In my opinion, it would be better if each fish was different but had a similar purpose. For example, you could have four fishes that help a tempo or control gameplan. This way, the randomness adds variety without making the game all about high and low rolls.

For the cards themselves, they look good to go. Goldie Friend should probably be a Beast tho. I'd love to see more !
