You win in fatigue because you have armour up and more cards in deck. You also discover a card every turn so you can get something that might help end the game faster.

If you ever played fatigue warrior theres a point where the game is won but the opponent still plays it out because they are mad or dont understand they cant comeback. This is just one of the downsides to the deck archtype.

Its a 3 card combo. You play togglewaggle with explore ungoro same turn with giest in hand. If they swap you blow up thier deck. If they dont swap well you cycle so fast you should have a big fatigue advantage, and your deck is only removal so they have no way to kill you.

Its just a new way to play fatigue warrior. Better vs razakus priest.
