It can fairly safely be assumed that this guy is not getting any of the three moves that don't have a Pokemon. Genosekuto is like a mini Arceus, but it doesn't work out that well. I do however have afew movesets for this guy.
EVs: Attack, Special Attack, Speed Nature: Any neutral nature
Techno Buster: Holding the Water Cassette, as all the others arer horrible. This provides type coverage against Fire types.
X-Scissor: STAB. Physical to provide a mixed sweeper.
Flash Cannon/Ice Beam: STAB. Not very good type coverage however, which is why Ice Beam is a good option.
