Sorry if this isn't very good, it's my first deck.
Pokemon: 19
2 Mime Jr (CoL)
2-2 Slowking (H/S)
4-2-4 Gengar (TR)
1 Mr Mime (CoL)
2 Spiritomb (TR)
T/S/S: 26
4 Dual Ball
4 Rare Candy
4 Pokemon Communication
4 Junk Arm
3 Lost World
2 Juniper
2 Oak's New Theory
3 Seeker
2 Switch
4 Defender
Energy: 12
10 Psychic
2 Rescue
STRATEGY:
Get out Mime Jr. and Slowking as fast as possible. Also set up the Lost World Stadium. From there, use Slowking to see your opponent's top 3 cards in their deck. If you find a Pokemon, put it second. On your next turn, retreat or switch Slowking with Mime Jr. Use his attack, sending the Pokemon to the Lost Zone. Gengar can be used to send Pokemon faster just in case you can't use Mime Jr.
