PvE

Analysis

The Shadow boost doesn't do much for Shadow Weezing. It's still a mediocre Pokemon in that is arguably the most mediocre type in the entire game.

Offense

Best

Situational

Acid* offers the highest DPS with STAB, but is a legacy move.
Infestation falls behind but is still usable, while Rollout does no favors.
Tackle is inferior in every way.
Sludge Bomb is preferred for its STAB effectiveness against Grass-types
Shadow Ball is clearly superior to Dark Pulse; both share the same cooldown and coverage, but the former simply deals higher DPS.
Thunderbolt can offer coverage in some niche situations, but lacks STAB.

Defense

Best

Infestation can his opposing Psychic Types hard, while Rollout has the best neutral performance among Weezing's options.
Acid* is clearly superior to Tackle; both offer wide neutral coverage, but Acid’s defensive DPS is significantly higher.
Shadow Ball deals higher DPS, but Dark Pulse’s damage window is a whole second earlier, increasing the chances of it actually connecting. Both offer valuable counter coverage against Psychic-types.
Sludge Bomb is a strong alternative, possessing an early damage window and wide neutral coverage.
Thunderbolt offers coverage but has a slightly longer damage window than Dark Pulse or Sludge Bomb.

Rollout and Infestation have similar stat-profiles, with the former sporting slightly higher energy generation and stronger neutral coverage, while the latter has Psychic Type counter-coverage.

As for Shadow Weezing’s charged moves, Sludge Bomb has okay neutral coverage and STAB. Shadow Ball had great neutral coverage and solid power. Thunderbolt has useful coverage against many common Water Types.
