Is Impostor Syndrome good in Commander?

Impostor Syndrome in Commander — Combos, Decks & Price

Impostor Syndrome turns a token copy of any creature into a persistent board presence — you get the enters-the-battlefield trigger, the activated abilities, and the stat line, all attached to a token that sticks around until the enchantment leaves. The catch is that the original creature gets exiled for as long as Impostor Syndrome stays in play, which means blinking or destroying the enchantment brings that creature back; against something like Aurelia, the Warleader, that's a feature, not a bug. Edea, Possessed Sorceress decks run it at over 40% inclusion because copying Edea herself doubles the token-generating engine without losing the commander to the command zone.

Best Commanders

Commanders with the highest synergy

01

Edea, Possessed Sorceress

40.3% of decks · synergy 0.39

Impostor Syndrome in an Edea, Possessed Sorceress deck lets you copy Edea herself, creating a second token-generating trigger engine without sending the original to the command zone — and because the enchantment exiles rather than kills, you're not paying commander tax when you want the real Edea back.

02

Felix Five-Boots

29.6% of decks · synergy 0.28

Felix Five-Boots cares deeply about connive and counters, and Impostor Syndrome slots in as a way to copy the highest-impact creature on the board — including Felix himself — to double up triggered abilities at instant speed with an enchantment that's harder to interact with than a creature.

03

Peter Parker

24.2% of decks · synergy 0.23

Peter Parker decks lean into role-assignment and copying effects, so Impostor Syndrome fits naturally as a way to replicate a key threat or commander ability while the original waits safely in exile rather than dying to removal.

04

Jin Sakai, Ghost of Tsushima

21.7% of decks · synergy 0.19

Jin Sakai, Ghost of Tsushima generates power by attacking and accumulating resources, and Impostor Syndrome extends that by letting the deck copy the most dangerous attacker on the board — including opposing commanders — to push through extra damage or steal an activated ability.

Format Analysis

Where it lives, where it can’t

Format	Verdict
commander	legal
legacy	legal
modern	legal
pioneer	legal
standard	legal
vintage	legal
pauper	not legal
oathbreaker	legal

Impostor Syndrome is legal in every major format except Pauper, but Commander is where it actually gets work done. In 60-card formats like Modern and Pioneer, four-mana enchantments that require a creature target compete with far faster threats, and the exile-until-removed clause creates too much dependency on the enchantment surviving a removal-heavy environment. In Legacy and Vintage the card is legal but irrelevant — the speed of those formats punishes anything that costs four mana and doesn't immediately win the game. Commander is the correct home: multiplayer games go long enough for the enchantment to generate real value, the card scales with the power of whatever creature it targets, and the political angle of exiling your own commander to reset it or copying an opponent's bomb is genuinely relevant at a 100-card table.
