Players can cast spells only during their own turns.
Dosan locks opponents out of instant-speed interaction by forcing all spells to be cast only on a player's own turn, then you leverage that protection to resolve threats, combos, and big mana plays unopposed. Ramp into Dosan early, deploy your engine while opponents sit helpless on their turns, and close before they can untap into answers. Mono-green gives you the acceleration and creature density to abuse the asymmetry.
Shuts off counterspells, removal, and combat tricks on your turn, making your spells effectively uncounterable and untargetable until opponents untap
Enables fragile combos and Voltron strategies to go off without instant-speed disruption
Mono-green ramp lets you cast Dosan and a payoff in the same turn for a sudden lock
Cheap commander (3 MV) that recasts easily and demands a hard removal answer
Symmetrical effect also stops YOUR instants on opponents' turns, hurting reactive plays
Dies to any spot removal or board wipe cast on the caster's own turn, instantly opening the window
Mono-green lacks card draw and counterplay outside of green's narrow toolkit
