I'm trying out a similar deck but I've found that it works better as less aggro and more comboy. Due to the way everyfin works, I try not to have too many murlocs that cost too much. Bluegill warrior is good for rushing but costs 1 more than the amount of murlocs you get down, as opposed to tidehunter. Point is, if you can already afford everyfin, tidehunter can be put down for free, gaining you a 4/3 and 3/3 on top of your board. Also, tinyfin is absolutely essential in this deck as it makes your extremely crucial spell come a turn early. It's not hard to have an insane board on turn 4-5 if you play your cards right.
