Leonardo, Worldly Warrior + Phyrexian Altar + Genesis Chamber + Angelic Sell-Sword

Leonardo, Worldly Warrior

Phyrexian Altar

Genesis Chamber

Angelic Sell-Sword

How it works

1. Cast Leonardo either from your hand or from the command zone by paying due to its cost reduction.
2. When Leonardo enters, Angelic Sell-Sword and Genesis Chamber trigger, creating two creature tokens.
3. Activate Phyrexian Altar by sacrificing Leonardo, adding .
4. Put Leonardo into the command zone from your graveyard.
5. Repeat.

This clever loop harnesses Leonardo, Worldly Warrior's built-in affinity for creatures to cast your commander repeatedly for just a single white mana. As Leonardo enters the battlefield, Genesis Chamber and Angelic Sell-Sword both trigger to flood your board with a steady stream of tokens, feeding the discount and padding your creature count. You then feed Leonardo right into Phyrexian Altar to sacrifice it for the mana needed to start all over again.
