What is this Raichu Stoutland deck you're talking about?
Essentially the key cards are
Raichu BUS
Stoutland BCR
Lillipup BLW (which is stoutlands basic)
Shining Celebi/celebi ex
Goodra from some set I forgot
Tropical beach stadium
Stoutland is a stage 2 while active prevents supporters from being played
Raichu paralyzes when evolved
Lillipup for an energy takes an item card put in into hand. You attack this way through celebi, which both cards let evos use attack from previous stages
Goodra is another stage two that stop your opponent from playing fool cards mainly used to prevent Garbotoxin
Tropical beach is you $200 stadium card that you play like 3-4 of and helps set up
You infinitely paralyze/supporter lock while reusing devolution spray and vs seekers for stuff like Cassius shauna az all stuff to recycle Raichu a ability and not deck out while your opponent slyowly runs out of cards with no way to shuffle them back in and they can’t attack cuz paralysis loop.
Tablemon did a deck profile/games on his channel on this deck a while back
No one would ever recommend playing this deck costs waaaaay to much and can brick hard
