Agatha of the Vile Cauldron + Cogwork Assembler + Sol Ring

Agatha of the Vile Cauldron

Cogwork Assembler

Sol Ring

How it works

1. Activate Cogwork Assembler by paying at most 2, creating a token copy of Sol Ring.
2. Activate the Sol Ring token by tapping it, adding CC.
3. Repeat.
4. If Agatha of the Vile Cauldron has power 6 or greater, this combo nets infinite mana and you can then target any other artifact(s) using Cogwork Assembler.

This clever loop turns Cogwork Assembler into a self-sustaining mana engine by leaning on Agatha of the Vile Cauldron to drastically slash activation costs. With Agatha’s power boosted to 6 or greater, the Assembler's steep {7} activation price drops to just {1}, allowing a single Sol Ring token to effortlessly pay for the ability that spawned it. By continuously copying your mana rocks, you generate infinite colorless mana to fuel any other artifacts you desire, while also leaving behind an endless army of hasty tokens.
