Clock of Omens + Biotransference + Stonybrook Schoolmaster

Clock of Omens

Biotransference

Stonybrook Schoolmaster

How it works

1. Activate Clock of Omens by tapping Stonybrook Schoolmaster and another artifact, targeting Stonybrook Schoolmaster.
2. Stonybrook Schoolmaster triggers, creating a 1/1 Merfolk Wizard creature token that is also an artifact due to Biotransference.
3. Resolve the Clock of Omens ability, untapping Stonybrook Schoolmaster.
4. Repeat.
