Marvin, Murderous Mimic + Pili-Pala + Greenweaver Druid

Marvin, Murderous Mimic

Pili-Pala

Greenweaver Druid

How it works

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

This clever engine turns Marvin, Murderous Mimic into a one-robot mana powerhouse by granting him the active talents of his peers. With Greenweaver Druid providing a generous burst of green mana whenever he taps, Marvin gains the ability to fund his own upkeep while leaving mana to spare. You then tap into Pili-Pala's unique untap symbol ability to reset Marvin for the cost of two generic mana, which is easily paid for using the surplus generated by the Druid. The result is an endless loop of tapping and untapping that churns out infinite colored mana for any format where these cards are legal.
