An ideal simple win might be something like. 2nd turn Liliana's Caress, 3rd turn Caress or Megrim, 4th turn they have 5+ cards in hand and you Collective Defiance or Dark Deal for lethal.
But other cool stuff can happen where you have 1-2 Waste Nots out and make them drop their hand, which triggers you drawing cards and getting enough mana to play a Liliana's Caress and another card to drop their hand for 14 damage followed by a Burning Inquiry for game. And that's like the main intent, getting "when your opponent discards..." effects out and playing stuff like Dark Deal, Collective Defiance and Burning Inquiry to deal a bunch of damage and get cool effects with Waste Not, Tourach and the Bowmasters.
