I like this card a lot, but my god is it overtuned... there's no reason to not just play this in literally every deck, it doesn't even matter if it's agro, control, combo or midrange deck. Even if this just had a "Roaring Oceans" as a battlecry it'd be a mainstay (so long as Shaman as a class wasn't completely trash).

To be fair though, I don't necessarily mind the power level on it, it's strong but doesn't seem like it'd be particularly unfun to play against IMO.

You can use Shape the Stars to copy an opponent's minion, making it an extremely powerful option. Imagine copying Thaddius, Monstrosity? "Vision of heroes" is also a much better option than you realize, it's good against aggro opponents, where it will often impact the board more than removing two minions would (and heal you in the process), or when you're ahead on tempo, in which case you can just play it, summon a minion, and if they don't have direct removal for your Aman'Thul you're basically guaranteed it goes off again, and you effectively lock the opponent out of the game. It's definitely the most situational of the three options, but far from useless! 

This is also the Titan that's probably the most likely to survive the turn of all the Titans they've showed so far, so even if not all the abilities are on the same power level, they're all fairly relevant.

I think you're way off the mark on this one. If you pick Swift Slash you basically equip an Ashbringer, with a slight upside of "immune while attacking". This is basically just a straight up better Tirion Fordring. Fair enough, Tirion isn't a particularly powerful minion by this point, but this comes down a whole two turns earlier and lets you attack immediately. I think Aggramar, the Avenger makes a perfect top-end for an aggro hunter deck, whenever that's a deck, this will be a staple of it. It deals half the opponent's life total in damage by itself, and an agro deck actually has a decent chance of having enough board that the opponent won't be able to remove this, and you get some minor extra value from it.

It may not be incredible, but it's damn good IMO.

This is a 4 mana 5/6 on curve, that's borderline playable outside of an Overheal deck, will definitely be interesting to give the archetype another try.

This is insanely strong removal. Literally all of these are well worth spending 5 mana on. Now the only thing left to be seen is whether a Demon Hunter deck that's enough on the control side of things to make use of this is viable.

Interesting card, very similar to Bronze Warden. I wouldn't be surprised to see this become a mainstay in a lot of DK and Paladin decks, it's really hard to remove without transform effects, and if you're just using it to trade with minions it will deal 12 damage before it's gone. It's also two divine shields for cards like Jitterbug and Funkfin. Looks somewhat unassuming at first but I think it's really strong.

Interesting card, I think it'll be better in a 2 Unholy / 1 Frost deck than Rainbow DK. Can make an interesting combo with cards like Cage Head. Realistically it likely won't be strong enough to play over any of the 3-rune decks, but that's okay, not every deck has to be competitively viable.

This is effectively a 4 mana 5/4 draw 2 cards, BUT it requires you to have drawn a weapon, and on average discards a card that's better than the three you're gonna draw (as weapons are generally among the more efficient/versatile cards for their costs. 

I will be very surprised if this actually sees any play, unless there's some crazy synergy with it in the miniset.

I'm aware Curse of Agony is rotating out, I just found it to be kind of a cute interaction (in wild), I only threw it in as an afterthought.

You play this with the other "fatigue" cards Warlock is getting. A really good curve would be something like: 

• Turn 2: Play a 3/3 Baritone Imp
• Turn 3: Play a 2 damage Crescendo
• Turn 4: Play Felstring Harp and a 5/5 Baritone Imp
• Turn 5: Play a Crazed Conductor that summons 4 3/3 Imps

Obviously you have to get quite lucky to get a curve as good as that or better, but the potential is pretty massive, and even if you spread it out more throughout the game, all the cards _after_ the first provide pretty great value independently.

Bonus points if your opponent plays Curse of Agony.

For the most part, but at least Felstring Harp can be played in any Control Warlock deck, even if you just use it to tap it's basically healing you for 12 damage - you heal 6 instead of taking 6. It's also just a 8 card package (6 if you discount Felstring Harp), which isn't unreasonable, most packages in Hearthstone have at least as many cards.

"will never get support in a later expansion"? You realize that the support you mention is literally "a minion with a tribe". How are they not going to get any tribed minions? This is a very, very good card whenever there's minions with different tribes that are good on their own that see play in Warrior. Doesn't need any other kind of support.

It's also not hard to set it up so both minions die, you just use it when there's two that trade evenly, and as priest you can even buff one beforehand to ensure both die. 

Yeah the fact that Druid has to attack with the hero power is a major downside, they can't hit past taunt, and so far we also haven't seen additional cards that take advantage of you having an upgraded hero power like the ones mage has. Still definitely a very good card, but not as similar as it at first appears.

I get where you're coming from, the direction for warrior is definitely baffling, but Armour has always been part of Druid's class identity. Their hero power gains armour, and they've always had plenty of armour cards, all the way back to the original release of Hearthstone.
