Undefeated, she's good enough that people have started to talk
An old to-go box or Tupperware container will do fine
Pokemon Card Overview: Pokemon Card Strategy: So as far as strategy goes, because Groudon EX is a basic Pokemon card you won't need to use any other cards with this card
It could be fetching Rest In Peace to stop Karador, Ghost Chieftain from running wild, or Oblation to tuck Erebos, God of the Dead, or Mind's Eye to start drawing tons of cards
Add to that a free equip with every new Mouse, Rat, Squirrel, or Hamster that enters the battlefield, and you've got a sword that's way better than a similar rhyming piece of equipment
As my #3 choice, I would suggest that a tokens-matter build is best for the card
