Use “Main deck” rather than mainboard

The mainboard section should be renamed main deck. There is no such thing as a mainboard, sideboards are named after a real piece of furniture. Main deck is best practice in magic coverage. Mainboard is commonly used, but still a mistake, similar to “alot” versus “a lot”. I realize this is pedantic, but technically it’s correct.

Where are you seeing mainboard?

“View Full History” and then the “Board” column.

Shame on me for missing this when I was searching for this exact thing when we were transitioning over to the proper term a while back. Thank you!
