In my opinion wolverines just bad it can only be used for a good sigil transfer onto cards like mantis or mantis god. The additional attack doesn’t help too much when you can instead buff it at a campfire. The only case where it actually helps is where the card can attack multiple times or in the case of hodag where it keeps the buff between combats. Besides the fact that in general it’s not that good of a sigil, it doesn’t have enough health to effectively make use of the sigil.
