Kiki-Jiki, Mirror Breaker card art
Kiki-Jiki, Mirror Breaker wins games on the spot the moment it touches the battlefield — tap it with Zealous Conscripts in play and you have infinite hasty tokens before anyone gets priority. The cost is the mana value: five mana and legendary status mean it needs a deck built to protect it, and commanders like Obeka, Brute Chronologist that exploit end-step triggers get disproportionate value from even a single activation.

Best Commanders

Commanders with the highest synergy

01
Obeka, Brute Chronologist

Obeka, Brute Chronologist

55.4% of decks · synergy 0.54

Kiki-Jiki, Mirror Breaker's tokens normally exile at end of turn — Obeka, Brute Chronologist simply ends the turn before that trigger resolves, leaving the copies on the battlefield permanently and converting every activation into free, recursive value.

02
Muxus, Goblin Grandee

Muxus, Goblin Grandee

63.9% of decks · synergy 0.53

Muxus, Goblin Grandee is already a goblin engine that floods the board on resolution, and Kiki-Jiki, Mirror Breaker turns each subsequent Muxus activation into two triggers — the copy can attack or tap before the token vanishes, often closing the game immediately.

03
Wort, Boggart Auntie

Wort, Boggart Auntie

53.5% of decks · synergy 0.49

Wort, Boggart Auntie wants as many goblins in the graveyard as possible for recursion, and Kiki-Jiki, Mirror Breaker feeds that engine while also serving as an independent threat that can copy any nontoken creature Wort returns to play.

04
The Master, Multiplied

The Master, Multiplied

51.0% of decks · synergy 0.47

The Master, Multiplied cares about creating token copies of legendary creatures, and Kiki-Jiki, Mirror Breaker is exactly that effect on a stick — each activation syncs directly with what The Master, Multiplied is trying to do at a mechanical level, stacking triggers and multiplying board presence.

05
Grenzo, Dungeon Warden

Grenzo, Dungeon Warden

48.7% of decks · synergy 0.44

Grenzo, Dungeon Warden mills creatures into play off the bottom of the library, and Kiki-Jiki, Mirror Breaker can copy whatever Grenzo drops — letting the deck double up on any high-value creature that hits without needing to cast it a second time.

Format Analysis

Where it lives, where it can’t

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

Commander is where Kiki-Jiki, Mirror Breaker is most at home: the singleton format slows the game down enough that a five-mana legendary creature can stabilize, and the density of enter-the-battlefield creatures and combo enablers like Zealous Conscripts makes the payoff immediate and consistent. In Legacy, Kiki-Jiki, Mirror Breaker is legal but rarely played — the format moves too fast for a five-mana creature without protection, and combo decks have cheaper, more resilient lines. Vintage is similar: it's technically legal, but the raw power of the format leaves little room for a five-drop that needs a second piece. Modern has historically hosted Kiki-Jiki, Mirror Breaker in dedicated combo shells, though its presence there has faded as faster alternatives emerged. If you're picking it up, Commander is the target.

Price Context

Current price

unknown tier

Kiki-Jiki, Mirror Breaker has been reprinted several times across premium products, which has kept the price accessible relative to its combo density — check current listings on Scryfall or TCGPlayer for the exact number, as foil and non-foil versions vary meaningfully. Given how many Commander decks across Goblin tribal, creature-copy, and infinite-combo strategies want exactly one copy, it's a steady demand card rather than a spike-prone one.
