Twinflame + Priest of Urabrask + Fork + Archaeomancer

Twinflame

Priest of Urabrask

Fork

Archaeomancer

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

This dynamic loop hinges on perpetually copying a single Twinflame to continuously multiply your board state while generating a net surplus of red mana. As Priest of Urabrask enters the battlefield, its triggered ability provides the fuel by adding three red mana, more than paying for the copy of Fork needed to repeat the sequence. Meanwhile, Archaeomancer anchors the entire engine by retrieving that exact Fork from your graveyard every single iteration. By layering these triggers together, you weave an endless cycle that yields infinite haste-granting tokens, mana, and triggers.
