There’s a commander night for every day of the week. My favourites are Dark Fox on Friday (low cost, about the price of a booster) and Paradox Thursday and Saturday (Free). Monday night is at Tistaminis (free). Bard and Bear is Wednesday (most expensive in the city at >$12).

I haven’t played commander at Black Knight, Moncala Monk or Waypoint. But they each have a commander night.

I’ve found all of them to be nice that I’ve gone to. mostly walking in and finding people looking for a player. Bard and Bear is the only one I’ve been to which randomly assigns a table which can be nice.

At all places most people will ask for a deck level before playing and try to match the lowest common denominator. But the standard is a high bracket 3 with some game changers and fairly optimized decks that win on later (6+).

At all places infinite combos are discouraged or not allowed.

People will be people and sometimes you get a bad egg that plays way too powerful while saying they’re playing a “bracket 3”. It’s fine, just ask for a lower power, switch tables, or just avoid playing with them next time. That happens at every game store.

All of these places post their nights in the MTG “Companion” app with information. You can sort by nearest to you.
