Summoning Station + Mycosynth Lattice + Phyrexian Altar

Summoning Station

Mycosynth Lattice

Phyrexian Altar

How it works

1. Activate Summoning Station by tapping it, creating a 2/2 Pincher creature token.
2. Activate Phyrexian Altar by sacrificing the Pincher, adding one mana of any color.
3. Summoning Station triggers, untapping itself.
4. Repeat.

This elegant loop turns Mycosynth Lattice into the ultimate universal catalyst by turning every permanent on the battlefield into an artifact, meaning even creatures like the tokens generated by Summoning Station carry that artifact type. Because of this sweeping transformation, sacrificing those Pincher tokens to Phyrexian Altar to generate mana will instantly trigger Summoning Station's ability to untap itself. You can thus endlessly spin this mechanical engine to churn out infinite colored mana, infinite sacrifices, and endless creature triggers.
