Is Experiment Twelve good in Commander?

Experiment Twelve in Commander — Combos, Decks & Price

Experiment Twelve enters the battlefield as a copy of any non-Human creature you control, giving you an immediate doubling of your best threat for four mana. In Kaust, Eyes of the Glade decks especially, that baseline is already a morph or manifest — so the copy lands with upside baked in.

Format Analysis

Where it lives, where it can’t

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

Experiment Twelve is a Commander card in practice — the morph and manifest synergies it slots into exist almost exclusively in that format's singleton environment. In Legacy and Vintage it's technically legal but has no competitive home; four mana for a Clone variant doesn't clear the bar in formats where the game ends before that matters. Oathbreaker is the one fringe case where it could see play, assuming a spellslinger or creature-copy commander, but the pool is small enough that it rarely comes up. Play Experiment Twelve in Commander, full stop.

Price Context

Current price

$0.37 bulk tier

At $0.37, Experiment Twelve is firmly bulk — it costs less than a sleeve and should be easy to pick up in any trade binder or bulk bin. Bulk rares with narrow synergy profiles don't tend to climb unless a new commander breaks them wide open, so buy it for the deck it fits and don't expect the price to move.
