Simply put...
You are limited to 1x
Sensoriality (
Unique Legend ) to play an extra card for 2 fights with 1 character...
But can have 3x Soul Characters playing an extra card EVERY fight + Sensoriality... It's no wonder that Shroom decks are massively OP...
I just have to wonder how many "Shrooms" whoever thought this was a good idea had beforehand...
