Runerigus

Runerigus sits at a 0.01% single use rate, ranked 239th, making it a fringe pick barely seen in standard play. The Ground/Ghost typing grants a deep physical side, taking 0.25x from Poison and 0.5x from Rock and Bug, with full immunities to Normal, Fighting, and Electric hits that define most physical cores. The 145 Defense and 105 Special Defense back those resistances, but 30 Speed and 50 Special Attack lock it out of most mid-speed matchups and strip it of any offensive presence beyond STAB and utility. The package asks for careful team support to function at all.

Playstyle：Gameplay revolves around Will-O-Wisp at 23.1% and Trick Room at 22.5%, splitting the role between wearing down physical attackers and reversing the speed tier under Trick Room. Spreads concentrate on Impish 41.6% and Sassy 32.3%, both dumping EVs into Defense and Special Defense and leaving Speed at zero to lock in as a Trick Room user. Items follow the same logic: Sitrus Berry 55.9% patches HP recovery, Mental Herb 32.5% protects against sleep and Taunt, and Zoom Lens 7.6% appears only on the small Poltergeist-focused builds.

Doubles usage sits at 0.07%, ranked 201st, still fringe but more visible than in singles. Its niche value is twofold: anchoring Trick Room teams with its 30 Speed and using its immunities to Normal, Fighting, and Electric to absorb common spread moves that threaten physical walls. The 145/105 bulk lets it take a STAB hit and reply with Poltergeist or Body Press under the Trick Room turns.

Playstyle：Doubles builds centre on Trick Room 20.8% with Poltergeist 11.0% as the slow retaliator, Ally Switch 10.6% to protect positional advantage under TR, and Will-O-Wisp 10.3% to soften key physical attackers. Items reflect that role: Colbur Berry 28.6% patches Dark weakness, Kasib Berry 15.5% covers Ghost, Leftovers 18.3% and Sitrus Berry 19.2% sustain HP, and Spell Tag 7.2% powers up Poltergeist. The defensive Sassy and Relaxed spreads both keep Speed at zero to act last under Trick Room.
