This elegant loop begins the moment you trigger any initial lifegain, drawing the divine attention of Heliod, Sun-Crowned to place a +1/+1 counter on Invisible Woman, Sue Storm or another Hero you control. That influx of counters activates Invisible Woman's trigger, bringing a fresh 0/4 Wall token into existence to pad your defenses. The very presence of that new arrival causes Soul's Attendant to notice and reward you with a point of life. Because that life gain immediately restarts Heliod, Sun-Crowned's blessing, the cycle spins endlessly into an infinite cascade of counters, tokens, and life.
