Just lose your Zombies in combat, sacrifice engines, and mass removal like Damnation and replace them
Necropotence gives you a great devils bargain: dump in a bunch of life, draw 20-35 cards in your end step, and hope to untap so you can win the game
Dont be afraid to add multiple copies of each card too, as the last thing you want is to be left vulnerable because your Toon Kingdom was destroyed after one turn
How did you prepare for the meta, and would you change anything going forward
Deep-Cavern Bat gives you useful information about whats in your opponents hand, and exiles a key card from it so long as the Bat remains on the battlefield
Just remember that its essential to consider your own playstyle and what you want to get out of the game
