Sword of Hearth and Home + Combat Celebrant + Tannuk, Steadfast Second

Sword of Hearth and Home

Combat Celebrant

Tannuk, Steadfast Second

How it works

1. Declare the creature with Sword of Hearth and Home and Combat Celebrant as attackers, choosing to exert Combat Celebrant as it attacks.
2. Combat Celebrant triggers, untapping all other creatures you control and causing you to get an additional combat phase after this one.
3. Deal combat damage to an opponent using the creature that has Sword of Hearth and Home attached.
4. Sword of Hearth and Home triggers, exiling Combat Celebrant, then causing you to search your library for a basic land card, then put the land and Combat Celebrant onto the battlefield.
5. Repeat each combat phase.

This clever sequence lets you chain endless combat steps by perpetually blinking away your key attacker with Sword of Hearth and Home whenever it connects with a player. Because Combat Celebrant is granted haste by Tannuk, Steadfast Second, it can safely attack and be exerted during every single one of these newly generated phases to untap your board. Crucially, the sword's exile-and-return effect resets Combat Celebrant's exertion state upon re-entry, allowing it to be exerted fresh over and over again.
