mtg commander deck bundle Magic: The Gathering Duskmourn Haunts & Horrors Pack card deck Wizards of The Coast Magic:

Most surge cards are creatures or have high costs that may prevent abuse (Fall of the Titans, Crush of Tentacles), but they are out there

Finale of Devastation finds you pretty much whatever you need throughout the game and in the later stages offers a pretty easy kill condition

Reanimation is also a good plan for mill decks, and cards like Virtue of Persistence or The Soul Stone should find their way into mill decks, if only to disrupt reanimation targets or use powerful milled pieces for your own gain

Complexity creep is one hell of a drug

Token and counter doublers along with proliferate effects can all work together to make a Fungus deck at least playable in low to mid-power Commander games

Theres also potential for Grim Tutor to make a big impact as it enters Standard, Pioneer and Modern
