Anointed Procession

How it works

1. Cast Lithoform Engine by paying 4.
2. LIthoform Engine enters the battlefield, triggering Cadric.
3. Holding priority, activate Lithoform Engine's first ability by paying 1 and tapping it, copying Cadric's trigger.
4. Activate Krark-Clan Ironworks by sacrificing Lithoform Engine, adding CC.
5. Resolve the copy of Cadric's trigger, causing you to pay 1 to create two token copies of Lithoform Engine.
6. Repeat from step 3.
