You forgot the part "Mime jr is now asleep" but who cares[FREE] Lost Sleep
Take the card on the top of your opponent's deck, and place it in the Lost Zone.
About the Gengar, a part of the attack is hidden so the attack looks like strange. I think the attack refers to some energies attached to Gengar who must be moved in to the Lost Zone with the Pokémon you have chosen.

Alright, these aren't 100% perfect translations, but here is what I've got!
Gengar:
Pokepower: Catastrophe
As long as this Pokemon is your Active Pokemon, if you knock out an opposing pokemon, place that pokemon in the Lost Zone. Place all cards attached to that pokemon in the discard pile.
Keep in mind that if Gengar has no good secondary attack, it wont matter.
Stage 2.. no thanks.
It also doesn't do what Claydol does.
No ofcourse it doesnt do what Claydol does, but hey, Claydol doesnt do what Pidgeot FRLG does right? At least we will have some draw engine and even if its Stage 2, it is better then lolDodrio/Noctowl.
