Marvin, Murderous Mimic card art
Marvin, Murderous Mimic copies any nonland permanent that enters the battlefield alongside it, turning every creature drop into a potential clone of your best threat — for just two mana. The catch is that the copy dies at end of turn, so you're trading permanence for immediate impact, which makes Marvin, Murderous Mimic a staple in shells like Ioreth of the Healing House that generate repeated ETB triggers, and a natural fit for Arcum Dagsson lines that care about artifacts entering play on demand.

51.6% of decks · synergy 0.50

51.1% of decks · synergy 0.49

Mairsil, the Pretender

47.5% of decks · synergy 0.47

Mairsil, the Pretender exiles cards to cage their abilities, and Marvin, Murderous Mimic gives Mairsil decks a copycat effect that can mirror a critical permanent for one all-important turn before the copy is gone.

Format Analysis

Where it lives, where it can’t

FormatVerdict
commander legal
legacy legal
modern legal
pioneer legal
standard legal
vintage legal
pauper not legal
oathbreaker legal

Marvin, Murderous Mimic is legal across every major Constructed format — Commander, Legacy, Modern, Pioneer, Standard, Vintage, and Oathbreaker — though only Commander is where it meaningfully shows up. In singleton formats, the ability to copy any nonland permanent on entry is exponentially more valuable because you can't run four copies of your best threat; Marvin, Murderous Mimic fills that redundancy role cheaply. In Constructed formats like Modern or Legacy, two mana for a temporary copy competes poorly against Clone effects with more lasting impact or faster win conditions, so it rarely makes those 60-card lists. Commander is the format this card was built for.
