 No problem, Sorry as I misread Unread Captain as A Dreadsteed like effect. Good work anyway.

New Murloc Class Cards

I wanted to give each Class which doesn't have a Murloc, a Murloc.

Hunter

Rouge

 Warlock

 Druid

 Warrior

 Mage

 Priest

 This is just for fun and in no means expected to be good. Also sorry if this would create more agro in the game.

I'm going to review each card.

Undead Captain- Is this a Battlecry, Deathrattle or Inspire. Kinda Important. Also legendary minions are normal reserved for named important WoW characters.

Undead Parrot- Which one can you add too your deck, also they probably aren't pirates, more likely beasts or undead if that tribe ever becomes a thing.

Trusty Flintlock- Just look at Powermace to see how bad this is.

Bolt Launcher- Cheap Longbow, I'll take it. Many make it a 4 mana 3/3 so it kills more things.

Vengeful Parrot- Playable card, its effect is more of a Priest thing and it should be a beast not Pirate.

Loot Pile- Probably should be At the start of your turn other wise you get a coin straight away and basically requires the opponent too kill it otherwise you get 2 more coins. Also make it Epic not Legendary.

Southsea Looter- The most overpowered card out of all of them, it is basically a Harrison Jones with +1 health, You steal there weapon And you can put 2 in a deck AND it locks the opponent out from playing more weapons as it keeps going. Maybe make it a 4/4 or 3/5 at least.

Young Privateer- Not the best, Wisp with +1 attack for Warrior.

Vicious Buccaneer- One of the better 1 drops, can be instakilled by 3 out of 9 classes.

Southsea Reinforcer- Pretty Average, probably change it to friendly pirates as buffing ALL minions is reserved for Murloc's.

Bloodsail Commander- Worst card here, overpriced, bad stats, maybe a 7 mana 4/8 would work better.

Empowering Corsair- Pretty average, might be better as a rouge natural with +1 Health.

Lost treasure- It's pretty well designed, saving 3 or 4 mana for later turns, paladins don't normally have a good turn 3 so it could be good.

Corsair Recruiter- Pretty good card, Good way to get your Southsea Captain in your hand.

Pirate Hoard- Pretty OP, Good finisher no couterplay.

Bloodsail Berserker- Basically Gruul But worse, also why is it a legendary.

Blacksea Summoner- Pretty good, slightly worse than Dragon consort as it could reduce your Young Privater but other than that, pretty good.

Greedy Captain- Good stats for a 1 mana card (Basically) and good idea. Once again, shouldn't be legendary

Southsea Buccaneer- Very well designed, very balanced.

Loot chest- I can see decks being built around this and being very overpowered, good either way.

Corsair Leader- Very well balanced, change its name to Jake Arrow and its a very good Legendary worthy effect.

Wild Grenadier- Is this a Battlecry, Deathrattle, Inspire?

Blacksea Recruiter- Not a very viable effect as it ruins combos and the flow of the game, maybe 5 mana 5/4 Deathrattle: Copy a random minion from your opponents hand into your hand. 

Overall quite well designed ill give you a 7/10

Just a thing you might what it change their rarity for arena and when writing Taunt or Stealth always put then in a line of their own. Also put a : after Battlecry, Deathrattle and Enrage. Example.

Not much of a change but at least to gets better buffs from spell damage.

I am more than a fish

A Fun card. Could win you 1 in 100 games.

I god damn hate rouge sometimes. I'm on 12 HP and have a full heath Ironbark Protector on the board and Dr Boom with 1 Boom Bot alive.

And the rouges all like Prep, Double Excavate and Double SI7 Agent,
WWWWWWWWWWWWWWWWWWWTTTTTTTTTTTTTTTTTFFFFFFFFFFFFFFFFF 

A silly And Annoying weapon.
