Raid (the Fridge) — At the beginning of your second main phase, if you attacked this turn, put a +1/+1 counter on target creature and create a Food token.
Partner—Character select (You can have two commanders if both have this ability.)
Michelangelo is a cheap mono-green aggro engine: attack every turn, then in your second main phase grow a creature with a +1/+1 counter and bank a Food token. Curve out, attack relentlessly, and snowball your board with counters while using Food as repeatable lifegain/sacrifice fuel, eventually closing with trampling beaters or a +1/+1 counter payoff.
Two-mana commander means he's online turn 2 and easy to recast through removal
Free repeatable +1/+1 counter every combat fuels counters-matter and snowball strategies
Food tokens give incidental lifegain, sac fodder, and synergy with artifact/Food payoffs
Trample lets him and buffed creatures push damage through chump blockers
Partner—Character select lets you pair him for color expansion and extra synergy
Mono-green lacks interaction, removal, and card selection compared to other colors
Reward only triggers if you actually attack, so stalled boards shut him off
Low base stats (he's small) make him a poor standalone threat
Vulnerable to board wipes that erase your counter investment
Food and counter payoffs require building around them or they're just value with no closer
