Yes, for sure!
Reuniclus:
Role: Bulky Sweeper
Item: Shell Bell
Nature: Modest
Moveset: Future Sight, Trick Room, Signal Beam, Recover
Future Sight/Recover: Used to deal lots of STAB. You could use psychic, but I like this more because it goes well with recover. He's too bulky to faint in two turns so after future sight is used, use recover to make up for the damage done during the two where he was vonurable.
Signal Beam/Shadowball: To cover dark type weakness, plus has the chance to confuse. Shadowball is just a solid move that covers the Ghost weakness, so it's up to you which one you like.
Trick Room: Obvious reasons, makes him fast
