I've been trying out the limited amount of free mons I got in ranked BSS and found out that Gliscor still kinda got it.
Gliscor @ No Item / Yache Berry
Ability: Hyper Cutter / Sand Veil
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Swords Dance
- Earthquake
- Acrobatics / Dual Wingbeat
- Thunder Fang / Rock Slide / Ice Fang
Gliscor was a great mon back in DPP even without Poison Heal so hey, why not try and run it anyway.
No item with Acrobatics lets you use a strong Flying STAB, but Yache Berry + Dual Wingbeat is a great option to tank a M-Lopunny Ice Punch and retaliate back. Thunder Fang hits Corviknight, Skarmory, Pelipper, and other Flyings and Waters in general hard. Alternatively, Rock Slide is a more general move that can hit the likes of Dragonite but doesn't cover Corviknight or Skarmory. It scores an OHKO on Charizard most notably although you're slower and get OHKOed by Fire Blast anyway. Ice Fang hits Garchomp and Dragonite the hardest. Hyper Cutter is quite nice when everyone has Arcanine early, and you can even run Sand Veil along a Tyranitar to fish for haxx.
Gliscor has a great matchup against a LOT of physical attackers like Tyranitar, Mega Bee, the Heracross everyone starts with, and countless others. Gliscor be doing Gliscor things, you know.
