Leoconters combo by Jaxxx2309

Format: Commander

Commander: Donatello, the Brains and Leonardo, the Balance

Bracket: 3

Deck overview

This is a five-color (WUBRG) +1/+1 counter and token engine deck helmed by the partner pair Donatello, the Brains and Leonardo, the Balance. Donatello doubles every token created - including the deck's signature Mutagen tokens - while Leonardo converts each token ETB into a global +1/+1 counter burst on your whole board. The plan is to flood the battlefield with Mutagen tokens (artifacts that sacrifice to put counters on creatures), then multiply those counters through Doubling Season, Branching Evolution, Hardened Scales, and Michelangelo, Weirdness to 11 until the engine detonates. Primary wins are All Will Be One converting every counter event into direct damage, Simic Ascendancy's 20-growth-counter alt-win, and overwhelming combat where Raphael, the Muscle doubles damage and Najeela, the Blade-Blossom chains extra combats. Marchesa, the Black Rose and Eerie Ultimatum provide a deep recursion backbone.
