First of all, this deck is meant to be cheap, as the dust price is raising across the board with all the quests and epics running around.
So, to play this deck properly, you need to most of the time think at least one turn ahead, as you have so many stealth minions, they usually will connect, so you have to always try to figure it out some way to find lethal in the next turns.
Most of the time make favorable trades, you lack on removal so once you loose the board, or you find a good Nourish or its just game.
Match ups & Mulli
agroo: most of the time its going to be some level of mirror, so try to take the board.
Quest: early drops and rush them so no value will come out of the queen
Mullingam (quest): early drops along with Wrath for board control and avoid them to finding a good adapt
MidRange: you usually cant win the attiction game, so make trades only if very favorable. If he finds a good unleash theres no much you can do.
Mulligan (midr): early drops n Wrath
