BlueLegendary Creature — Human Mutant ShapeshifterIrma, Part-Time Mutant
Mana value3Rank#5,065
The Commander
At the beginning of combat on your turn, Irma becomes a copy of up to one other target creature you control, except her name is Irma, Part-Time Mutant and she has this ability. Then put a +1/+1 counter on her.
Guide
Gameplan
Each combat, Irma copies your best creature you control and stacks a +1/+1 counter, so you build a board of strong creatures and turn Irma into a growing second copy of whatever matters most that turn. You ramp into and protect key value creatures, then either swing wide/tall or chain copy effects and ETB triggers for value. The +1/+1 counters make her a credible threat even when copying small utility bodies.
Strengths
- Free clone every combat lets her mirror your strongest or most synergistic creature without spending cards
- Steadily accumulates +1/+1 counters, so she grows into a real beater regardless of what she copies
- Works with any creature you control, giving huge flexibility and resilience to board states
- Mono-blue gives access to elite counterspells, card draw, and tutors for consistency
Weaknesses
- Mono-blue lacks efficient removal and struggles against resolved problematic permanents
- Copy only triggers in combat on your turn, so she's slow and does nothing the turn she enters
- Heavy reliance on having a good creature already in play; an empty or wiped board makes her ability worthless
- Commander-damage and counter strategies fold to single-target removal and board wipes
Key Cards
- Sakashima of a Thousand Faces — A copy-themed legend that pairs perfectly with clone synergies and ETB value Irma can mimic.
- Spark Double — Another body that copies your best creature, doubling the value engine Irma already provides.
- Aether Channeler — Strong ETB body worth copying repeatedly for tokens, bounce, or extra mana.
- Doubling Season — Doubles the +1/+1 counters Irma generates each combat, accelerating her into a lethal threat.
- Hardened Scales — Cheap counter amplifier that makes every Irma combat trigger more impactful.
- Cyclonic Rift — Mono-blue's premier catch-up button to protect your board and clear opposition before swinging.
Upgrade Path
Add counter doublers (Doubling Season, Hardened Scales, Branching Evolution) and proliferate effects to weaponize her per-turn counter, plus strong ETB creatures worth copying. Tighten the manabase with fast mana (Sol Ring, Mana Crystal, Mana Vault) and add protection like Lightning Greaves and Heroic Intervention to keep Irma online. Lean into counterspell density and tutors (Mystical Tutor, Fabricate) to find your best copy targets and answer threats reliably.
