Marnie SR and Piers SR from S4a Shiny Star V have been officially revealed. These are reprinted cards of Marnie and Piers Supporter cards from previous Sword & Shield sets.
The artwork features both characters in the Galar League uniform. These seem to be based from their League Cards in the Videogame, where they also wear the same uniform. Marnie (set number 198) has been illustrated by Naoki Saito, Piers (set number 194) has been illustrated by Megumi Mizutani.
The S/SSR/SR/HR(?)/UR cards will be revealed next week on Wednesday, so make sure to look again on PokeGuardian next week on Wednesday!
