I was holding a blank Carriss, I played Corpsicle and it didn’t lock in the frost buff for Carriss and say 1 left. Did it several times as corpsicle returned, no dice. Note the corpsicle may have been discovered off Thrive in the Shadows or its copy from the naga which gives you a copy from the next spell you draw. I was surprised to get a copy, because i thought discovering a copy wasn’t drawing it? So 2 bugs in 1 game?
Do you have a replay by chance?
