Again, just because it has a murloc tag doesn't mean you need to run murlocs.

It's a perfectly fine 2 drop in a dragon deck.

 Except that it's tiny and slow because it's a deathrattle. I'd honestly rather run Faerie Dragon and maybe my class's Breath spell or something.

 I have to disagree here. Yes, I might run Faerie Dragon anyway. But playing a 2/2 on turn 2 that dies and gives a dragon +2/+2 is pretty good. There are not a lot of good 2 drops right now for a Paladin dragon deck... there's Cathedral Gargoyle (which I bet will be tried out) and also Firetree Witchdoctor... I might run this instead of the Witchdoctor. So many spells are junk (Secrets etc).

 Let's imagine you play this on turn 2, it dies, and you buff a 3 drop in your hand. Suddenly your 3 mana Nightmare Amalgam is a 5/6 instead of a 3/4, or your Bronze Explorer is 4/5 instead of 2/3. That's really good tempo-wise for turn 3. 

I think I'll be trying this card out.

Funny you should mention Cathedral Gargoyle, because it is almost strictly better than Tasty Flyfish in exactly the scenario you described.

Why? Because you'll have initiative with the 2/2 body if your opponent traded into it on the previous turn. The extra 2/2 stats on a turn-3 Amalgam wouldn't have that, nor would you be able to split your attack if you need to.

Are these weird tribe mixes being printed for Battlegrounds?

I hope so, because that is the only context in which I find the idea interesting.
