Absol

The Disaster Pokemon has one of the highest Atk stats of Gen 3, but otherwise doesn’t have much in the way of stats. Absol doesn’t quite reach the power of many of the better Dark Types, but it’s still a... usable... raid attacker. Regardless, it might be worth raising one in the future, as Mega Absol is a glass cannon of a Pokemon that could be very useful moving forward.

Best PvE Offensive Moveset

• Snarl is superior to Psycho Cut due to having STAB and more relevant coverage.
• Dark Pulse is superior to both Megahorn and Thunder for similar reasons.
• Payback is a step down. 

Best PvE Defensive Moveset

• Snarl is superior to Psycho Cut due to its significantly higher base damage.
• Dark Pulse is superior to Megahorn due to having STAB, an earlier dodge window, slightly better coverage, and a lower energy cost.
• Payback is a downgrade due to it being a 1-bar move. 
• Thunder also has an early dodge window, but is underwhelming in every aspect.

Snarl falls behind Psycho Cut slightly in energy gains, but offers significantly more damage output thanks to STAB. The latter can be chosen if that slightly extra energy generation is needed. 

Dark Pulse costs the least amount of energy and benefits from STAB to provide Dark-type coverage. Payback is less desirable due to its greater energy cost. Megahorn provides Bug-type coverage and costs slightly less energy than Thunder, while the latter offers Electric-type coverage. Either can be chosen depending on what coverage would be more preferable.
