Twinflame + Priest of Urabrask + Scholar of the Ages + Increasing Vengeance

Twinflame

Priest of Urabrask

Scholar of the Ages

Increasing Vengeance

How it works

1. Cast Twinflame by paying 3, targeting any two creatures.
2. Holding priority, cast Increasing Vengeance by paying its mana cost, copying Twinflame, with the copy targeting Priest of Urabrask and Scholar of the Ages.
3. Resolve the copy of Twinflame, creating a token copy of Priest of Urabrask and Scholar of the Ages with haste.
4. When the Priest of Urabrask and Scholar of the Ages tokens enter, they trigger.
5. Resolve the Priest of Urabrask trigger, adding .
6. Resolve the Scholar of the Ages trigger, returning Increasing Vengeance from your graveyard to your hand.
7. Repeat from step 2.

This brilliant loop begins by supercharging Twinflame with Increasing Vengeance, allowing you to instantly duplicate your engine pieces the moment they hit the board. As your newly copied Priest of Urabrask enters the battlefield to refund the mana needed to keep the chain alive, the accompanying Scholar of the Ages recursion grabs your graveyard resources right back to hand. Because Increasing Vengeance can continually copy these spells (and even fuel itself directly from the graveyard later via flashback), this recursive cascade endlessly spits out haste-granting tokens while generating infinite red mana.
