Twinflame + Priest of Urabrask + Fork + Zealous Lorecaster

Twinflame

Priest of Urabrask

Fork

Zealous Lorecaster

How it works

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

This brilliant loop uses Twinflame to kickstart a cascade of copies, letting a single initial investment balloon out of control. As Priest of Urabrask enters the battlefield, its entry trigger provides the vital red mana needed to keep the cycle running, while Zealous Lorecaster ensures Fork is conveniently retrieved from your graveyard to copy Twinflame all over again. By repeatedly replaying and copying the spells, you generate an endless supply of hasty creature tokens alongside infinite mana.
