Invisible Woman, Sue Storm + Light of Promise + Impassioned Orator

Invisible Woman, Sue Storm

Light of Promise

Impassioned Orator

How it works

1. Gain life.
2. The other Hero triggers, putting a +1/+1 counter on it
3. Invisible Woman triggers, creating a creature token.
4. When the creature token enters the battlefield, Impassioned Orator triggers, causing you to gain 1 life.
5. Repeat from step 2.

This self-sustaining loop spins into infinity the moment you trigger a single instance of lifegain, which Light of Promise turns into a +1/+1 counter for its enchanted creature. Because that creature is another Hero under your control, Invisible Woman, Sue Storm's triggered ability steps in to generate a 0/4 colorless Wall creature token with defender whenever counters are placed. The arrival of that new token immediately causes Impassioned Orator to trigger, feeding you back the 1 life needed to restart the entire cycle.
