Mondrak, Glory Dominus + Phyrexian Altar + Sacred Mesa

Mondrak, Glory Dominus

Phyrexian Altar

Sacred Mesa

How it works

1. Activate Sacred Mesa by paying 1, creating two 1/1 Pegasus creature tokens.
2. Activate Phyrexian Altar twice by sacrificing both Pegasus, adding 1.
3. Repeat.

This loop turns a modest stable of winged steeds into an infinite engine of faith and metal. With Mondrak, Glory Dominus doubling your production to two Pegasus tokens for every activation of Sacred Mesa, you have exactly the fuel needed to feed Phyrexian Altar twice. Sacrificing both tokens to the Altar generates the exact mana required to immediately restart the cycle, letting you farm infinite enter-the-battlefield, death, and sacrifice triggers on command.
