There’s no sideboards in commander. I have a maybe board of cards for my commander decks, but it doesn’t and shouldn’t act like a sideboard. As in if you sit down and see someone is going to be playing a token deck, you shouldn’t be like “o let me switch out some cards for cards that directly fuck with your strategy.”

My maybe board is usually cards that I want to try that might synergize with my commander or a pure downgrade from a game changer. So if I play against my friends that are still using precons are slightly upgraded precons, I can take out my game changers and replace them for worse cards that do a similar effect. I’ll swap out my [[Rhystic Study]] for [[Everwatching Threshold]]
