Phyrexian Ironfoot + Nyxbloom Ancient + Paradise Mantle

Phyrexian Ironfoot

Nyxbloom Ancient

Paradise Mantle

How it works

1. Activate Phyrexian Ironfoot by tapping it, adding three snow mana of any color.
2. Activate Phyrexian Ironfoot by paying 1S, untapping it.
3. Repeat.

This clever loop transforms Phyrexian Ironfoot into a self-sustaining mana engine by turning its activation cost into a profitable venture. By outfitting the construct with a Paradise Mantle, tapping it no longer just struggles against its refusal to untap naturally, but instead yields a massive surge of mana thanks to Nyxbloom Ancient tripling the output of any permanent you tap for mana. With that tripled yield, you easily pay the snow mana required to untap Phyrexian Ironfoot and repeat the process, leaving you with an endless surplus of colored and snow mana to fuel the rest of your game plan.
