Agatha of the Vile Cauldron + Cogwork Assembler + Mana Vault

Agatha of the Vile Cauldron

Cogwork Assembler

Mana Vault

How it works

1. Activate Cogwork Assembler by paying at most 3, creating a token copy of Mana Vault.
2. Activate the Mana Vault token by tapping it, adding CCC.
3. Repeat.
4. If Agatha of the Vile Cauldron has power 5 or greater, this combo nets infinite mana and you can then target any other artifact(s) using Cogwork Assembler.

By stacking Agatha of the Vile Cauldron's power-based cost reduction onto the table, we slash the daunting activation cost of Cogwork Assembler down to a mere three mana. This turns Cogwork Assembler's token-copy ability into a bargain that can be fueled entirely by tapping the newly created Mana Vault token for three colorless mana. Because that copied Mana Vault enters untapped and ready to use, you can repeatedly copy it to generate infinite colorless mana, and then pivot those endless resources into flooding the board with infinite copies of any artifact or creature you desire, complete with haste.
