Syrix, Carrier of the Flame + Skyfire Phoenix + Phyrexian Altar + Pitiless Plunderer

Syrix, Carrier of the Flame

Skyfire Phoenix

Phyrexian Altar

Pitiless Plunderer

How it works

1. Activate Phyrexian Altar by sacrificing Syrix, adding 1.
2. Choose not to move Syrix from your graveyard to the command zone.
3. Syrix dies, triggering Pitiless Plunderer, creating a Treasure token.
4. Activate Phyrexian Altar by sacrificing Skyfire Phoenix, adding 1.
5. Skyfire Phoenix dies, triggering Syrix and Pitiless Plunderer.
6. Resolve the Pitiless Plunderer trigger, creating a Treasure token.
7. Activate both Treasure tokens by tapping and sacrificing them, adding .
8. Resolve the Syrix trigger, causing you to pay 2 to cast Syrix from your graveyard.
9. Skyfire Phoenix triggers, returning itself from your graveyard to the battlefield.
10. Repeat.

This ingenious loop turns your graveyard into a perpetual engine of fiery rebirth, centered around sacrificing Syrix, Carrier of the Flame and Skyfire Phoenix to Phyrexian Altar. While the Altar and Pitiless Plunderer generate the mana and Treasure tokens needed to fund the operation, Skyfire Phoenix's ability to return itself whenever you cast your commander ensures your costs are constantly met. Meanwhile, Syrix, Carrier of the Flame provides both the recursion trigger to recast itself from the graveyard and the ultimate payoff, burning your opponents to ashes with every iteration of this avian cycle.
