look for the shark, and card draw.  Keep 1-2 aoe minions early to respond to early agression.  Don't try to go all in on turn 1 and 2 but don't play it 2 greedy either.

Mulligan:

Always keep: chest, shark, minstrel, 1 aoe, countess ashmourn.

If you have shark: keep bonemare, maybe fungle



So the main idea is you want to buff your shark early and draw some cards then just kill em on turn 4 or so.

Try to keep their boards clear as they can really buff their boards.  Dream start would be something like turn 2 shark, minstrel, coin bonemare on the shark.

Now they can't remove it with aoe and next turn you can draw a full hand and make a huge board at the same time.

Trust your card draws don't be afraid to go in a turn early.  But what you don't want to do is like tempo shark thinking it's safe with sealth and get instantly aoe'ed that's stupid.  Also you don't want to do something like shark coin bonemare on turn 1 as on turn 2 you won't have enough mana to take advantage of they shark then they just vile spine it and you're probably lost.
