I cast Planar Incision on my Vadrik, Astral Archmage in response to Brazen Borrower's adventure. It was my commander so the game prompted me as to whether to put it in the command zone. I Declined. It was exiled with a +1/+1 counter but remained there. Brazen Borrower fizzled and went to the graveyard. I passed the turn and Vadrik remained exiled. I conceded, as I could not win given my spell permanently exiled my commander instead of rescuing it...
