General  misassumption: Discard deck does not base on megrim or lilana caress to win the game. It wins by destroying opponents gameplay while you build your game. The damage from megrims are only a bonus. Discarding opponents hand should be happening as soon as possible and not when megrim is in game.

Strategy: Discard opponents hand as fast as possible  -> Put him under your enchament effects and relying on his draw-step -> control the game until he loses all his life -> win the game

Opponent will try to stack cards to cancel enchament effects, whenever he does punish him with more discard and pain (with liliana carres )

Your deck is creatureless so be sure to kill all cheap creatures from early game with creature-board-wipes like pyroclams or else you will lose too much life to survive late game. Save terminates for creature-bombs in midgame.

Desecration Demon- threat bonus
