Salamence is completely outclassed as a dragon dancer, and many mega Metagross run grass knot, so quagsire is a shaky check at best.Here are some of my suggestions:
- Mega Garchomp under SD users
- Quagsire under Mega Metagross checks
- Gyarados under Keldeo checks
- Mega Gardevoir under Mega Sableye checks
- Ferrothorn under Landorus-T checks
- Rhyperior under Dragon-type checks (best counter to Zard X)
- Toxicroak under priority
- Toxicroak under Keldeo checks
- Pangoro under wallbreakers
- Zygarde under Other Set Up (Coil)
- Salamence under Choice Scarf users
- Salamence under Dragon Dance
- Dragonite under Keldeo checks
- Latias-Mega under Keldeo checks
- Sceptile-Mega under Keldeo checks
- Mega Glalie under wallbreakers
My suggestions
- Hydreigon to wall breakers and choice scarfers
- Haxorus to Dragon dancers and stall breakers
- Celebi to nasty plot
- Remove cloyeter. It's unviable.
- Add mega Loppuny checks section
- Add weather inducers section
- add cleric section
- add diglet to trappers (lol jk)
A few of my suggestions, good luck with this project.
