Twilight Drover + Phyrexian Altar + Primal Vigor

Twilight Drover

Phyrexian Altar

Primal Vigor

How it works

1. Activate Twilight Drover by paying 2 and removing a +1/+1 counter from it, creating four 1/1 Spirit creature tokens with flying.
2. Activate Phyrexian Altar three times by sacrificing three Spirits, adding 2.
3. When the Spirits die, Twilight Drover triggers three times, putting six +1/+1 counters on itself.
4. Repeat.

This brilliant loop is built on a compounding geometric engine powered by Primal Vigor, which doubles both the Spirit tokens we create and the +1/+1 counters we receive. We kick things off by activating Twilight Drover, whose ability is fueled by the mana from sacrificing just three of those resulting tokens to Phyrexian Altar. As those spirits leave the battlefield, Twilight Drover triggers to collect a flurry of counters—which Primal Vigor doubles—leaving our elemental weaver bigger and stronger after every single iteration.
