Heliolisk

Heliolisk sits at 0.09% usage in singles, ranked 170, well outside the standard ladder conversation. Dry Skin accounts for 96% of ability picks, so it is functionally a one-ability mon. The 49 base Speed leaves it outsped by most of the 109 Speed tier it nominally belongs to, and 55 Atk / 52 Def push it toward the special side. It checks electric and flying hits at half damage and walls normal and fighting entirely through its Ghost typing, which gives it niche value as a specialist switch-in. The lack of offensive presence keeps it on the fringe.

Playstyle：The standard build runs Choice Scarf with a Timid nature and full investment into SpA and Spe, with the two main spreads together covering 93.4% of sets. The goal is straightforward: leverage the effective 109 Speed to outspeed most of the 100-base tier. Shuca Berry at 21.9% patches the ground weakness, while Bright Powder at 10.5% hedges against Earthquake predictions in singles. The move pool splits between Grass Knot at 22.2% and Thunderbolt at 21.8% to hit standard switch-ins, Shed Tail at 18.4% to hand off a safe switch to partners like Scizor and Mimikyu, and Dragon Pulse at 18.3% to keep Dragon-typed walls honest.

Doubles usage sits at 0.33% and rank 112, still fringe but noticeably more present than in singles. The ability split of 80% Dry Skin and 18.2% Solar Power shows that players invest in different traits for different team contexts. Choice Scarf at 52.8% leads items, with Focus Sash at 23.2%, meaning it serves both as a scarfer and a lead. The 109 Speed tier is the main reason it keeps a foothold in doubles, outpacing most unboosted threats.

Playstyle：In doubles the move pool is led by Thunderbolt at 18.1% and Hyper Voice at 13.4%. The latter hits both opposing slots, which is why it edges out alternatives like Discharge and Grass Knot. Shed Tail at 9.1%, Volt Switch at 8.6%, and Protect at 8.5% make up the tempo toolkit: Shed Tail passes a safe switch to a backline threat, Volt Switch rotates positioning, and Protect scouts opponent priorities.
