OP's Deck

This is a mono-green Commander deck built as a +1/+1 counters ramp/combo deck. It uses fast mana, mana dorks, and powerful lands like Gaea’s Cradle and Nykthos to accelerate quickly, then stacks counter-doubling effects such as Hardened Scales, Branching Evolution, Doubling Season, Vorinclex, and Ozolith, the Shattered Spire to grow creatures explosively.

Its key synergies revolve around modular/scalable threats like Walking Ballista, Hangarback Walker, Stonecoil Serpent, and counter engines like Rishkar, Kami of Whispered Hopes, Evolution Sage, and The Ozolith. Agatha’s Soul Cauldron and proliferate effects add extra value, while Inkmoth Nexus offers an alternate infect kill by piling on counters. The deck usually wins by creating huge board presence, generating massive mana, and finishing with an oversized Walking Ballista, a giant Finale of Devastation attack, or a heavily boosted creature/infect threat.
