The magic behind this loop lies in Maskwood Nexus, whose passive ability grants every creature you control—and every creature card you own outside the battlefield—every creature type simultaneously. Because Maskwood Nexus turns Wirewood Symbiote into an Elf even while it is in your hand, you can recast the Symbiote for a single green mana after returning it to your hand. By using Wirewood Symbiote's activated ability to untap a creature that taps for mana, you generate a surplus of green resources to fund that very casting cost. This creates a self-sustaining cycle that yields infinite creature enters-the-battlefield and leaves-the-battlefield triggers, along with an astronomical storm count.
