Bone Miser + Blood Speaker + Mind Over Matter + Arcane Adaptation

Bone Miser

Blood Speaker

Mind Over Matter

Arcane Adaptation

How it works

1. Activate Mind over Matter by discarding Blood Speaker.
2. Bone Miser's first ability triggers, creating a 2/2 Zombie creature token that enters the battlefield as a Demon due to Arcane Adaptation.
3. Blood Speaker's second ability triggers, returning itself to your hand from your graveyard.
4. Resolve the Mind over Matter ability, untapping target artifact, land or creature.
5. Repeat.

This elegant loop turns the raw discarding power of Mind Over Matter into an engine of endless value by routing it through Bone Miser, which generates mana, cards, and Zombie tokens whenever you part with a card. The genius that locks this engine into a permanent loop is Arcane Adaptation, which redefines your entire deck and battlefield as Demons so that every Zombie token entering triggers Blood Speaker's graveyard-to-hand retrieval. That retrieved Blood Speaker then feeds right back into Mind Over Matter as your discard fodder, letting you endlessly churn out your entire library, infinite mana, and an infinite army of Demon Zombies.
