A stall build centered on Umbreon's Inner Focus pivoting with Yawn/Wish support and Toxapex's Haze-plus-Toxic Spikes stalling, gradually grinding the opponent down. Glimmora's Stealth Rock and Chesnaught's Synthesis recovery sustain the team through the long game. Built for cycling attrition rather than raw sweeping power, it holds up reasonably well even against physical attackers like Garchomp.
Umbreon (Leftovers, Inner Focus): Foul Play / Protect / Wish / Yawn. Runs a healing cycle with Yawn and Wish while Inner Focus voids Trick and Taunt-style disruption.
Mega Delphox (Blaze): Fire Blast / Psychic / Protect / Encore. Encore locks down the opponent's setup or hazard move before switching into a firepower turn.
Glimmora (Focus Sash, Toxic Debris): Toxic / Mud Shot / Energy Ball / Stealth Rock. The lead that reliably sets Stealth Rock, using Focus Sash to survive even a check.
Mimikyu (Choice Scarf, Disguise): Play Rough / Will-O-Wisp / Trick / Destiny Bond. A support trapper that uses Scarf Trick to lock down the opponent's key attacker's speed.
Toxapex (Sitrus Berry, Regenerator): Toxic Spikes / Toxic / Haze / Recover. Toxic Spikes plus Haze force switches while Regenerator keeps it from ever truly going down.
Mega Chesnaught (Bulletproof): Body Press / Leech Seed / Iron Defense / Synthesis. Stacks Iron Defense before counterattacking with Body Press as the final wall, and Bulletproof keeps it safe from ball and bomb moves.
