Combat Celebrant + Displacer Kitten + Spellbinder + Fires of Yavimaya

Combat Celebrant

Displacer Kitten

Spellbinder

Fires of Yavimaya

How it works

1. Declare Combat Celebrant and the creature with Spellbinder attached as attackers, choosing to exert Combat Celebrant as it attacks.
2. Combat Celebrant triggers, causing you to untap all other creatures you control and to get an additional combat phase after this one.
3. Deal combat damage using the creature that has Spellbinder attached.
4. Spellbinder triggers, causing you to copy a card exiled with it, and cast the copy without paying its mana cost.
5. Displacer Kitten triggers, blinking Combat Celebrant.
6. Resolve the spell cast in step 4.
7. Repeat each combat phase.

This explosive loop turns the relentless pressure of Combat Celebrant into an endless chain of combat phases, fueled entirely by the static haste granted by Fires of Yavimaya so your troops can swing the very moment they arrive. While your equipped creature connects to trigger Spellbinder and cast a free instant from exile, Displacer Kitten watches for those noncreature casts to blink Combat Celebrant back to the battlefield—wiping away its exertion mark entirely and allowing you to exert it anew in the next combat phase.
