drampa pokemon card holo TCG (Japanese) - GX Full Art 042/051 Pokemon - Sword & Shield

The emblem it generates puts +1/+1 counters on a target artifact and, if its not already also a creature, makes it into a Robot creature

Yasharn seems like a powerful inclusion in basically any deck that isn't hosed by its effects, so any budgetish deck not running fetchlands but especially decks like Gaddock Teeg Hatebears or Captain Sisay which can tutor up this legendary as a silver bullet

Therefore, it proves to be a sniping goldmine against Fighting and Water-type cards, as well as cards having Electric-type as a weakness

Pollen Lullaby or Scattering Stroke might be the best options

Attack 1: [FFF1] Gaia Volcano (100+)
