Activate Crown of Flames' second ability by paying , returning it from the battlefield to your hand.

This loop is a masterclass in turning a humble one-mana Aura into a glittering engine of destruction. By casting Crown of Flames, you trigger Chishiro, the Shattered Blade to spawn a Spirit, but thanks to Mondrak, Glory Dominus doubling your token creation, you actually get a pair of 2/2 menaces instead of just one. Those two fresh tokens can immediately be fed to Phyrexian Altar to generate the exact red mana needed to bounce Crown of Flames right back to your hand. Repeat the process, and you have an endless cycle of re-casting, doubling, and sacrificing that floods the board and the graveyard alike.
