Elite Arcanist + Chakram Retriever + Pact of the Titan + Terror of the Peaks

Elite Arcanist

Chakram Retriever

Pact of the Titan

Terror of the Peaks

How it works

1. Activate Elite Arcanist by paying 0 and tapping it, casting a copy of Pact of the Titan without paying its mana cost.
2. Chakram Retriever triggers, untapping Elite Arcanist.
3. Resolve Pact of the Titan, creating a 4/4 Giant creature token.When the Giant enters the battlefield, Terror of the Peaks triggers, dealing damage equal to the Giant's power to any target.
4. Repeat.

This loop turns free creature-making into an explosive engine by looping spells through Elite Arcanist with a zero-cost instant like Pact of the Titan imprinted onto it. Every time you cast that copy, Chakram Retriever's triggered ability steps in to untap the Arcanist so you can immediately repeat the process. Meanwhile, the steady parade of Giant tokens entering the battlefield causes Terror of the Peaks to rain down lethal damage to any target of your choosing, closing out the game on the spot.
