Twinflame + Priest of Urabrask + Scholar of the Ages + Return the Favor

Twinflame

Priest of Urabrask

Scholar of the Ages

Return the Favor

How it works

1. Cast Twinflame by paying 3, targeting any two creatures.
2. Holding priority, cast Return the Favor 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 Return the Favor from your graveyard to your hand.
7. Repeat from step 2.

This clever loop relies on copying a strived spell to generate a self-sustaining cycle of resources. You kick things off by casting Twinflame to target two creatures, then immediately use Return the Favor to copy it and target a Priest of Urabrask and a Scholar of the Ages. As those two tokens enter the battlefield, the Priest of Urabrask triggers to supply the red mana needed to keep going, while the Scholar of the Ages conveniently plucks Return the Favor right back out of your graveyard. By repeating this process, you create an infinite army of hasty tokens alongside limitless mana and storm count.
