Kadabra @ Life Orb
Ability: Magic Guard
EVs:252 SpA / 4 SpD / 252 Spe
IVs:0 Atk- Encore
- Hidden Power [Ground]
- Shadow Ball
Additional Move Options: Hidden Power [Fighting], Substitute, Dazzling Gleam, Energy Ball, Psyshock, Thunder Wave, Calm Mind, Magic Coat
Notes: Encore allows you to switch into passive moves including hazards such as Stealth Rock as well as support options such as Leech seed and Toxic.
Encore is good against defensive threats like Probopass which can pivot with Volt Switch and Tangela which can tank a hit and break sash on common Sash Kadabra.
By forcing swaps through Encore against defensive Pokemon the momentum will be shifted in your favor, allowing free attacks or switches.
