They were a few floating around Ebay back in 2000
The first, Dusk Raid, hits for 110 and doubles to 220 the moment any of your benched Pokmon are carrying damage counters
The first of Gengar's moves is super powerful, for only one Psychic energy, Life Drain, allows you to put damage counters on the defending Pokemon until it is 10 hp away from feinting, so if you have a Pokemon that has 200 hp you can do 190 hp in one turn with one Psychic energy card, the only thing that is a downfall to this card is that you have to flip a coin to see if you can use this move at all, if you get heads you can if you get tails you can't, so you have a 50% chance of doing 190 hp damage, I would take that chance any day
Land Crush can do 130 damage on its own, but with an Arceus card in play, Land Crushs base damage goes up to 160
This character lets you be a bit more aggressive in your challenging or get back some of your early-game characters to keep your game going smoothly
