I saw the new Accelgor and thought this could work as a lock deck.
3 Shelmet (11 NV)
3 Accelgor (11 DE)
3 Oddish (60 UD)
1 Gloom (27 UD)
2 Vileplume (24 UD)
3 Sunkern (85 HGSS)
2 Sunflora (31 HGSS)
3 Virizion (13 NV)
2 Mewtwo EX (54 ND)
Pokemon: 22
3 Professor Oaks New Theory
4 Pokemon Collector
3 N
2 Professor Juniper
2 Twins
3 Rare Candy
3 Pokemon Communication
2 Pokemon Catcher
2 Skyarrow Bridge
T/S/S: 24
10 Grass
4 DCE
Energy: 14
Strategy: Setup up Vileplume Trainer Lock as quick as possible (just like every other lock deck) and get Sunflora out right after that. Then just use Sunflora to get an Accelgor swarm, and start the Accelgor Pokemon Lock. Shuffle the active into your deck, send out another Accelgor, or Virizion as a stall/secondary attacker, retreat to Accelgor (start setting up another with Sunflora) and repeat.
