These arent mechanically different to other cards with the same name in the Rise of the Floodborn set, but instead are visually spectacular and very hard to find alternate art variants
The set included Robin Hood, Captain Hook, Stitch, Cruella De Vil, Elsa and Mickey Mouse cards, along with two commemorative pins - its not yet clear if these same card versions will eventually appear in Lorcanas first main set
Silumgar Spell-Eater

Pokemon Card Strategy: So as far as strategy goes, since Skiploom is a a stage 1 Pokemon card that has a stage 2 evolution in this set I would recommend keeping Skiploom on the bench until you can evolve it into Jumpluff and then attack with Jumpluff, in the meantime make sure to add energy cards to Skiploom on the bench so if you need to put it into play you can attack right away
It can actually be pretty scary good
