Vs Shaman and priest use void contract, especially shaman.
Combo/Druid, fill up there hand and immolate OR play immolate on turn 3-4.
Everyone other matchup, try to mill/draw all your opponents cards THEN cast curse of agony with an elekk,vargoth, tasmin on board. Your curses should have stacked enough dmg that 6 agony draws is lethal.
Wicked shipment + phylastery + defile for giant mill turn (rarely have done this and just milled all or most of deck then gave them 6+ agony curses.
It's close to a strong deck but not quite there. Should probably toss out protector because i win a lot of games without using contract.
using cards like immolate/contract that dont instantly change board is good when you have customer in hand so you can clear next turn.
