Heres how this works, I'll say a pokemon and its move it can learn and next poster says another pokemon that can learn same move and another move it can learn e.g.:
Poster 1:
Pokemon: Gastly
Move: Nightmare
Poster 2:
Pokemon: Xatu (Can learn Nightmare)
Move: Wish
Poster 3:
Pokemon: Jirachi (Can learn Wish)
Move: Refresh
but the poster can't say move "Doom Desire" as only Jirachi can learn it and mew is not allowed as it can learn any TM/HM move.
ok, lets start:
Pokemon: Dragonite
Move: Swift
Poster 1:
Pokemon: Gastly
Move: Nightmare
Poster 2:
Pokemon: Xatu (Can learn Nightmare)
Move: Wish
Poster 3:
Pokemon: Jirachi (Can learn Wish)
Move: Refresh
but the poster can't say move "Doom Desire" as only Jirachi can learn it and mew is not allowed as it can learn any TM/HM move.
