Ground hits for ×2.56 — Nihilego's Rock/Poison typing is double-weak, so those attackers outperform their score gap.
Watch its Poison/Normal/Rock moves — counters like Sceptile (Mega) take super-effective damage from them.
Clear weather boosts Ground moves ×1.2 — the best time to battle Nihilego.

Rankings are estimated cycle DPS (attack stat × move damage ÷ cycle time, with STAB and type effectiveness). Not a full battle simulation.
