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

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