Elite Arcanist + Chakram Retriever + Pact of the Titan + Blasting Station

Elite Arcanist

Chakram Retriever

Pact of the Titan

Blasting Station

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, Blasting Station triggers, untapping Blasting Station.
4. Activate Blasting Station by tapping it and sacrificing the Giant, dealing 1 damage to any target.
5. Repeat.

This ingenious loop relies on Elite Arcanist imprinted with Pact of the Titan, allowing you to repeatedly cast the free spell to fuel your engine. Every time you cast that spell on your turn, Chakram Retriever untaps Elite Arcanist to keep the chain going while generating a 4/4 Giant token. Those entering creatures continuously trigger Blasting Station to untap itself, letting you sacrifice the freshly made Giants to ping away your opponents' life totals.
