Glissa, Herald of Predation

Krark-Clan Ironworks

Clock of Omens

How it works

1. At the beginning of your combat phase, Glissa triggers, choosing the first mode.
2. Holding priority, activate Lithoform Engine's first ability by paying 2 and tapping it, copying Glissa's trigger.
3. Resolve the copy of Glissa's trigger, creating two Incubator tokens.
4. Activate Clock of Omens by tapping the Incubators, untapping Lithoform Engine.
5. Activate Krark-Clan Ironworks by sacrificing an Incubator, adding CC.
6. Repeat from step 2.
