Additional Move Options: Toxic

Notes:
- Duosion is able to bypass Entry Hazards and Toxic, while using its defensive capabilities to set up Calm Mind and use Recover to set up and sweep.
- Signal Beam improves the matchup against Dark-types such as Shiftry and Liepard while still hitting Psychic-types for coverage compression.
- Preferably, late-game sweeping is possible when all Dark types and Knock Off users are out of play.
