Marvin, Murderous Mimic + Soliton + Doc Samson, Super Psychiatrist

Marvin, Murderous Mimic

Soliton

Doc Samson, Super Psychiatrist

How it works

1. Activate Marvin using Doc Samson's ability by tapping it, adding at least .
2. Activate Marvin using Soliton's ability by paying , untapping it.
3. Repeat.

This clever loop relies on Marvin, Murderous Mimic absorbing the crucial abilities of both Soliton and Doc Samson, Super Psychiatrist to turn a simple tap into a mana-generating engine. While Soliton's activated ability provides the essential untap capability for just one blue mana, Doc Samson, Super Psychiatrist fuels the loop by tapping for mana based on its power—a return that is further supercharged by its own replacement effect whenever counters get involved. By alternating between these borrowed traits, Marvin can continually tap for a surplus of mana and untap itself indefinitely, yielding infinite colored mana for your spells.
