Marvin, Murderous Mimic + Pili-Pala + Harabaz Druid

Marvin, Murderous Mimic

Pili-Pala

Harabaz Druid

How it works

1. Activate Marvin using Harabaz Druid's ability by tapping it, adding at least two mana of any color.
2. Activate Marvin using Pili-Pala's ability by paying 2 and untapping it, adding one mana of any color.
3. Repeat.

Marvin, Murderous Mimic acts as the ultimate chameleon here, stepping into the roles of your other creatures to assemble a self-contained mana engine. By copying Harabaz Druid, Marvin can tap to generate a surge of colored mana based on your allies, and then instantly pivot by adopting Pili-Pala's activated ability to untap itself for a modest two-mana fee. Because Pili-Pala's untap ability yields one mana while costing two to activate, the excess mana produced by Harabaz Druid easily bridges the gap, allowing you to cycle this process infinitely for boundless colored mana.
