Wirewood Symbiote + Mirror Entity + Viridian Joiner

Wirewood Symbiote

Mirror Entity

Viridian Joiner

How it works

1. Activate Viridian Joiner by tapping it, adding at least .
2. Cast Wirewood Symbiote by paying .
3. Activate Mirror Entity by paying 1, giving creatures you control all creature types and base power and toughness 1/1 until end of turn.
4. Activate Wirewood Symbiote by returning it from the battlefield to your hand, untapping Viridian Joiner.
5. Repeat.

This clever green loop turns a humble Elf and a humble druid into an engine for infinite mana and arbitrarily large statistics. Viridian Joiner serves as our primary mana producer, tapping to generate green mana based on its power, which is temporarily set by Mirror Entity's activation to accommodate the loop's mana needs. Meanwhile, Wirewood Symbiote provides the recurring bounce effect—thanks to Mirror Entity granting every creature type, the Symbiote can return itself to hand to untap the Joiner, resetting the process for a single green mana.
