The Ultimate Mono U Affinity Sideboarding Guide
Here's my Affinity sideboarding guide for the majority of the summer 2022 modern metagame, including all of tier 1 and some more obscure decks that I've had enough reps against to be familiar with.
Feel free to comment and ask if there are any matchups you'd like my opinion on, and have fun playing Affinity!
