Exalted Flamer of Tzeentch + Sundial of the Infinite + Warrior's Oath

Exalted Flamer of Tzeentch

Sundial of the Infinite

Warrior's Oath

How it works

1. Cast Warrior's Oath by paying .
2. Exalted Flamer of Tzeentch's second ability triggers, dealing 1 damage to each opponent.
3. Resolve Warrior's Oath, causing you to take an extra turn after this one.
4. Move to your extra turn.
5. At the beginning of your upkeep, Exalted Flamer of Tzeentch's first ability triggers, returning Warrior's Oath from your graveyard to your hand.
6. Repeat steps 1-3 one additional time.
7. At the beginning of your end step, Warrior's Oath triggers.
8. Holding priority, activate Sundial of the Infinite by paying 1 and tapping it, ending the turn and exiling the Warrior's Oath trigger from the stack.
9. Repeat from step 4.

This ingenious loop leverages the explosive extra turn potential of Warrior's Oath while deftly sidestepping its fatal penalty. As you cast the spell over and over, Exalted Flamer of Tzeentch punishes your opponents with its Fire of Tzeentch damage ability and ensures Warrior's Oath is conveniently bought back to your hand every single upkeep via Sorcerous Inspiration. Finally, Sundial of the Infinite acts as your safety valve, letting you prematurely end the turn to cleanly exile the looming game-losing trigger before it can resolve.
