Shadow Wailord

Shadow Wailord is... not great. Just leave it in the ocean where it belongs.

Best PvE Offensive Moveset

• Water Gun should be paired with Surf. This is Wailord’s only viable moveset on offense.

Best PvE Defensive Moveset

• Rollout is the best Fast Move option for Wailord on defense, though Zen Headbutt is... okay.
• Watergun is weak on defense.
• Scald is the Charged Move of choice, with Surf standing as basically the same move, but weaker.
• Hyper Beam and Blizzard are too weak.

Rollout has the best PvP performance among Wailord's Fast Moves.

Surf has a lower energy requirement, while Scald has supportive functionality thanks to its ability to debuff Attack. Return has strong neutral coverage and solid power, but it's also very costly. Hyper Beam takes this to an additional extreme, but is usable. Blizzard is also a nuke with counter-coverage.
