This delightful engine relies on Circle of Dreams Druid to turn your board state into a massive fountain of green mana, leveraging its ability to tap for {G} for each creature you control. To keep the mana flowing, Wirewood Symbiote uses its activated ability to untap the Druid by bouncing itself back to your hand, taking advantage of the fact that Mirror Entity’s changeling ability (and its {1} activation) ensures every creature on your side—including the Symbiote itself—is an Elf. Because Mirror Entity also grants all creature types, the recast Wirewood Symbiote counts as an Elf ready to be bounced right back to hand, creating a self-sustaining loop that nets infinite green mana, storm count, and creature triggers.
