This creature seems to be bugged as it somehow causes soft locks with seeding, making it unplayable.
Seed mechanic has been bugged from launch. It seems it is most likely a double triggering that goes bad, so the game can’t resolve which seed effect is performed first
I've noticed it only bugs my games when playing Kasmina pw. It works fine with the Seed Nissa pw.
Do you get the same behavior?
I have not identified the problem to one PW. I think it is a special case which depends upon some interaction, like seed twice combined with another effect such as “when you seed, seed again”.
Oracle of Mul Daya is still causing freezes, seems to be due to him because I was using other pma cards that don't freeze the game anymore.
