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.

+1/+1 Counters — Her built-in counter each turn synergizes with counter doublers and proliferate payoffs.
Voltron — With protection and counter accumulation she becomes an evasive beater dealing fast commander damage.
Control — Mono-blue counterspells and card draw let you stall while Irma quietly snowballs into a wincon.
