Mishra, Eminent One + Lithoform Engine + Ashnod's Altar

Mishra, Eminent One

Lithoform Engine

Ashnod's Altar

How it works

1. At the beginning of your combat phase, Mishra triggers, targeting any artifact.
2. Holding priority, activate Lithoform Engine's first ability by paying 2 and tapping it, copying Mishra's ability, targeting Lithoform Engine.
3. Resolve the copy of Mishra's ability, creating a token copy of Lithoform Engine that is a 4/4 creature with haste named Mishra's Warform in addition to its other types.
4. Activate Mishra's Warform's first ability by paying 2, and tapping it, copying Mishra's ability, targeting Lithoform Engine.
5. Holding priority, activate Ashnod's Altar by sacrificing Mishra's Warform, adding CC.
6. Repeat from step 3.
