Invalid Sideboard Error When Deck Has 15 Cards
Steps to reproduce the bug:
Open MTG Arena on PC and create a new deck.
Add your mainboard cards as normal.
Add exactly 15 cards to the sideboard.
Attempt to save the deck.
Platform:
PCActual results:
The client displays an error message:“Invalid deck: can't have more than 15 cards in a sideboard,”
even though there are only 15 cards in the sideboard. It prevents saving the deck.Expected results:
The deck should be valid and save successfully with 15 cards in the sideboard, as this is the maximum legal amount.Workaround:
Reducing the sideboard to 7 cards allows the deck to save, but this limits proper deck construction and is not a viable long-term solution.

Yep. Sideboarding has been bugged for a least a week with no comment from WotC on this match-breaking issue.
