How it works
Prerequisites
- An opponent cannot block creatures you control.
- You control an artifact creature.
Steps
- 1Deal combat damage to an opponent using Donatello and the creature that has Breath of Fury attached, triggering Donatello and Breath of Fury.
- 2Resolve the Donatello trigger, creating a token copy of the artifact creature.
- 3Resolve the Breath of Fury trigger, causing you to sacrifice the creature it is attached to, then attach Breath of Fury to the artifact creature token, then causing you to untap all creatures you control and to get an additional combat phase after this one.
- 4Repeat each combat phase
