Interesting card. It gives Murloc Shaman a lot of nice options, such as getting more board presence back after a lot of other Murlocs have been cleared by AoE, giving Murloc Tidecaller a lot of attack, and giving you a board full of sticky minions when combined with Coldlight Oracle. But the best part of all is the cost reduction on Everyfin Is Awesome, and if you're lucky enough to keep 3 murlocs on board before your opponent gets to drop an AoE, you're gonna have some serious board presence with all that. Definitely a good card to have in Arena too for the amount of board presence it gives you, though by themselves the summoned Murlocs can be removed easily. Overall, I rate it as Playable because I still don't know wether or not this is going to be enough to make Murloc Shaman popular.
