Suki's power is equal to the number of creatures you control.
Whenever Suki attacks, create a 1/1 white Ally creature token that's tapped and attacking.
Suki is a go-wide token aggro commander whose power scales with your board, so flood the battlefield with creatures and swing for huge variable damage. Each attack adds another tapped, attacking Ally token, which both pumps Suki and widens your assault. Build a wide board early, then convert it into a one-shot kill via combat tricks, anthems, or trample/double strike.
Free attacking token every combat snowballs board presence and Suki's power simultaneously
Cheap GW token engine that pairs naturally with anthems and go-wide payoffs
Self-sufficient: a single attack with even a modest board threatens lethal commander damage
Ally and creature-count synergies are abundant in green and white
Board wipes set you back hard since both Suki's power and your wide board collapse
Suki's power is zero on defense and she contributes nothing to blocking math
Needs evasion or trample to push damage past blockers on a clogged board
Relies on Suki connecting—removal or fogs can stall the whole plan
With a wide attacking board it comes online instantly and makes every creature a threat.
Add fast mana and efficient ramp (Sol Ring, Smothering Tithe, mana dorks) to deploy threats and finishers earlier. Lean into anthem and overrun effects—Craterhoof Behemoth, Triumph of the Hordes, and Cathars' Crusade—plus protection like Heroic Intervention and Teferi's Protection to survive board wipes. Tighten the curve with cheap token producers and a Skullclamp/Idol of Oblivion draw engine so you never run out of bodies.
