Twinflame + Priest of Urabrask + Mnemonic Wall + Return the Favor

Twinflame

Priest of Urabrask

Mnemonic Wall

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 Mnemonic Wall.
3. Resolve the copy of Twinflame, creating a token copy of Priest of Urabrask and Mnemonic Wall with haste.
4. When the Priest of Urabrask and Mnemonic Wall tokens enter, they trigger.
5. Resolve the Priest of Urabrask trigger, adding .
6. Resolve the Mnemonic Wall trigger, returning Return the Favor from your graveyard to your hand.
7. Repeat from step 2.

This explosive loop revolves around copying spells and recycling them to generate infinite resources on the spot. You kick things off by casting Twinflame to target two creatures, and then immediately copy it using Return the Favor. The resulting token copies of Priest of Urabrask and Mnemonic Wall enter the battlefield, where the Priest yields a burst of red mana to fuel your engine while the Wall safely returns Return the Favor from your graveyard straight back to your hand. By repeating this process, you can continually leverage Twinflame and Return the Favor to flood the board with infinite hasty tokens and endless red mana.
