I'm not sure a lot of you remember but a few years ago a Curator Warrior deck was a thing, and it's quite a fun deck to play. The deck has desperately needed at least a few Murlocs that could synergize with the rest of the other tribal tags, all they ran typically is just Finley but alas our prayers have been answered. This along with Skyfin are great additions to the deck and I'm excited to give it a whirl again especially after all the dragon and beast support given to us after all these years.
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.
Did anyone seriously consider running Void Analyst in a demon heavy deck? No. Why would dragon decks want this one then?
+2/+2 to one minion is better than +1/+1 to all the minions of a certain tribe in your hand. And I'm not saying it's a perfect card, just judging this on "I don't want to run Murlocs with my dragons" is not the right way to think about it IMO.
You can get a 5/4 Faerie Dragon or a 7/5 elusive wyrm using this. That's pretty good.
