Whenever a token you control enters, you may put a +1/+1 counter on each creature you control. Do this only once each turn.
: Creatures you control gain menace, trample, and lifelink until end of turn.
Partner—Character select (You can have two commanders if both have this ability.)
Leonardo turns any single token-maker into a board-wide +1/+1 counter pump every turn, snowballing a wide army into a tall one. You ramp into a token engine, drop Leonardo, and each turn quietly grow every creature you control, then untap and swing with menace/trample/lifelink via his five-mana activated ability to push through a lethal alpha strike.
Five-color identity unlocks every token-maker, counter synergy, and answer in the format
Free, repeatable board-wide pump that scales with even one token per turn
Built-in evasion and lifelink finisher lets a wide board punch through blockers and stabilize life
Partner—Character select gives flexible co-commanders and consistency redundancy
Counters survive board wipes better than tokens alone, and pair with proliferate/counter payoffs
Four colors of fixing is demanding; mana base must be excellent or the deck stumbles
Does nothing the turn he lands without a token already in play
The 'once each turn' clause caps the engine—extra tokens give no extra counters
Removal-heavy or fog-heavy tables blunt the go-wide plan
The WUBRG activated ability is mana-intensive and competes with developing your board
Cheap multiplier that amplifies every +1/+1 counter Leonardo distributes.
Prioritize a flawless mana base—fetches, duals, Triomes, and rocks like Arcane Signet and Chrome Mox—so four-plus colors are never a liability. Add token and counter multipliers (Doubling Season, Parallel Lives, Branching Evolution) plus proliferate engines to make every trigger overwhelming. For higher power, lean into fast mana, efficient token-storm enablers, and a compact combo finish such as a sac-outlet aristocrats loop to close before the table stabilizes.
