Long Feng, Grand Secretariat + Evolution Witness + Ugin's Conjurant

Long Feng, Grand Secretariat

Evolution Witness

Ugin's Conjurant

How it works

1. Cast Ugin's Conjurant by paying 0.
2. Ugin's Conjurant enters and dies as a state-based action due to having 0 toughness.
3. Long Feng triggers, putting a +1/+1 counter on Evolution Witness.
4. Evolution Witness triggers, returning Ugin's Conjurant from your graveyard to your hand.
5. Repeat.

This ingenious loop turns the fragile nature of Ugin's Conjurant—cast for zero mana so it immediately perishes as a state-based action—into a persistent engine by leaning on Long Feng, Grand Secretariat to catch the resulting death trigger. That trigger places a +1/+1 counter onto Evolution Witness, whose own triggered ability instantly snaps Ugin's Conjurant right back out of your graveyard and into your hand. By constantly recycling that zero-cost entry and exit, Evolution Witness triggers over and over again to endlessly fish back your cards while netting you an unlimited storm count and endless enters-the-battlefield triggers.
