Dynamax Sableye

Ah, Sableye... a fun little Pokemon, but one that rarely catches breaks... outside of PvP anyway. As a Dynamax Pokemon, Sableye is a bit underwhelming. Its Attack and bulk are pretty bad, so it doesn't do much in practice. It's an okay-ish defender when its resistances come into play, but all-in-all it's not great.

Best Dynamax Movesets

• Shadow Claw enables Max Phantasm and has the highest energy gains among Sableye's Fast Moves. Add to that the fact that Ghost and Dark have virtually identical coverage, and there's almost no reason to use Feint Attack... except for the rare moments where something is weak to Dark, but not Ghost.
• Shadow Claw is the option for Defense due to its higher energy generation.

In terms of PvP performance, Dynamax Pokemon are virtually identical to their non-Dynamax counterparts.
