Djinn Illuminatus + Pact of the Titan + Impact Tremors

Djinn Illuminatus

Pact of the Titan

Impact Tremors

How it works

1. Cast Pact of the Titan choosing to pay its replicate cost an arbitrarily large number of times, paying a total of 0.
2. Pact of the Titan's replicate ability triggers, causing you to copy Pact of the Titan for each time the replicate cost was paid.
3. Resolve the first Pact of the Titan, creating a 4/4 Giant creature token.
4. When the Giant enters the battlefield, Impact Tremors triggers, dealing 1 damage to each opponent.
5. Repeat from step 3 for each remaining Pact of the Titan.

This elegant and devastating loop is anchored by Djinn Illuminatus, whose static ability grants every instant and sorcery you cast the replicate keyword, matching its mana cost. When you cast Pact of the Titan, you can pay its zero-mana replicate cost an arbitrarily large number of times, generating an overwhelming hoard of copies that cost you nothing upfront. As each resulting 4/4 Giant token enters the battlefield, Impact Tremors triggers to rapidly ping your opponents to death, turning a free spell into a game-ending barrage.
