Gonk will always work as long as you have enough life. I mean, not playing any minions is not a win condition for any deck. I'm pretty sure Gonk decks also have Leeroy Jenkins specifically in the deck in case the opponents board isn't big enough.
You can also keep your opponent guessing what your win condition is if you don't have to play specific cards in a slower matchup. Most combo druid cards are 100% the same, except a few small changes like Pounce in Gonk.
