I'm going into the glass gauntlet soon, so here's my team:
Temple (Aegislash), don't know what item to give him ,swords dance, King shield, iron head, shadow sneak (my ace and sweeper, especially you Serra. Max Swords dance + ss equals gg.)
Scar (Incineroar), going to carry assault vest, brick break (for annoying screens), darkest lairat, flare blitz, fake out
Shelly (Lapras), mystic water/waterium z/ life orb, dive ( to scout moves and for special walls), hydro pump, perish song!!, freeze-dry. (I use shelly to tank while I heal up, and as a second backup for dragon types)
Skipper (Drapion), scope lens, night slash, cross poison, fell stinger, toxic (my second sweeper, because sniper N scope lens is a winning combo. Once she gets a critical hit...)
Cuddles (Mimikyu), spell tag, destiny bond, hone claws, shadow claw, play rough (my plan is to break the field and shadow claw away)
Sparkle (Ampharos), amphorasite, power gem (for shelly), light screen, discharge (to break field) dragon pulse
My Reserve:
Jumper the hawlucha, Cosmo the dragonite, Rex the tyrantrum, Nala the gardevoir, Blaze the typhlosion, Reuben the chandelure, Sickleworth the excadrill, Iago the malamar
