Scrafty

What're you lookin' at? (probably how bad Scrafty is in PvE) Ya got a problem? (only if you invest in Scrafty) Ya better not even think of messin' with THIS bad man (very bad) Ya better freakin' think twice (because you're basically throwing your dust away) before Scrafty messes ya up proper! (seriously; it'll mess up your dust bank).

Best PvE Offensive Moveset

• Snarl and Foul Play let Scrafty operate as a Dark attacker
• Counter and Power-Up Punch make for Scrafty's Fighting Type moveset.... though it's not great.
• Thunder Punch isn't great.
• Acid Spray is worthless on offense.

Best PvE Defensive Moveset

• Counter and Snarl have similar performance on defense.
• Power-Up Punch comes out quickly and frequently, making it a good defensive option.
• Thunder Punch is the same story, and it also has the advantage of hitting would-be Flying Type counters for Super Effective damage.
• Foul Play is stronger, but also slower.
• Acid Spray is worthless on defense, too.

Counter is recommended for its superior damage output by a considerable margin, in addition to its wide coverage. Snarl generates energy more quickly, but lacks raw power. 

Foul Play is the only significant damage-dealing charge move available, and benefits from STAB. Power-Up Punch is the cheapest charge move available energy-wise, and while it doesn't deal much damage, can be useful to boost ATK while possibly baiting shields. Acid Spray is an interesting utility charge move, but not as viable due to its somewhat expensive energy cost. Thunder Punch can offer coverage against some Water- and Flying-type Pokemon.
