Diamond Lion + Enduring Renewal + Akroma's Memorial

Diamond Lion

Enduring Renewal

Akroma's Memorial

How it works

1. Activate Diamond Lion by tapping it, sacrificing it and discarding your hand, adding three mana of any color.
2. Diamond Lion dies, triggering Enduring Renewal, returning Diamond Lion from your graveyard to your hand.
3. Cast Diamond Lion by paying 2.
4. Repeat.

This engine relies on Enduring Renewal's replacement effect and graveyard trigger to create an endless loop with Diamond Lion. Because Enduring Renewal returns creatures straight to your hand when they die, sacrificing Diamond Lion for three mana immediately feeds it back to you, leaving you plenty of resources to recast it for two mana and generate a net positive supply of colored mana. While Akroma's Memorial doesn't directly touch the mana-generating loop, its passive keywords grant your entire team vital traits like haste and flying to leverage the resulting infinite storm count and creature triggers the moment the loop concludes.
