Ganax, Astral Hunter + Realm-Scorcher Hellkite + Temur Sabertooth + Panharmonicon

Ganax, Astral Hunter

Realm-Scorcher Hellkite

Temur Sabertooth

Panharmonicon

How it works

1. Cast Realm-Scorcher Hellkite by paying 4 and sacrificing another artifact, enchantment or token.
2. When Realm-Scorcher Hellkite enters the battlefield, it and Ganax trigger twice.
3. Resolve both Realm-Scorcher Hellkite triggers, adding 5.
4. Resolve both Ganax triggers, creating two Treasure artifact tokens.
5. Activate Temur Sabertooth by paying 1, returning Realm-Scorcher Hellkite to your hand from the battlefield.
6. Repeat.
7. Once you have infinite Treasure tokens, you may sacrifice them for infinite mana, and use Realm-Scorcher Hellkite to deal infinite damage to any target(s).

This dynamic loop uses Ganax, Astral Hunter to turn the repetitive bouncing of Realm-Scorcher Hellkite into a net-positive treasure-generating engine. Panharmonicon doubles the entry triggers of your Dragons, ensuring that each iteration yields an excess of mana and treasure tokens to fuel Temur Sabertooth's activation cost. Once your mana and artifacts are infinite, you can simply keep casting the Hellkite to leverage its activated ability for infinite damage to any target.
