Your main win conditions are two. Your primary one is to outlast your opponent to then play every turn (in order): Raise Dead -> Educated Elekk -> School Spirits -> Soul Shear -> Hero Power/Drain Soul. This makes your hero always gain at least 8 Health per turn, which against decks who sturggle to apply more damage than that, will make you win. Your secondary one is to finish Lakkari Sacrifice to play it's reward and summon Imps every turn. Bonus if you play the Quest reward alongside the Elekk to have up to two portals.
