[Choice Scarf]
Yea, Genesect needs Thunderbolt on its Scarf set. Useful for revenging +1 Gyarados, which is still a dangerous threat in rain; without TB it's also getting walled by Tentacruel and Jellicent, which isn't exactly a good thing for a Volt-Turn core. Not being able to hurt defensive Politoed also sucks. Not to mention that without TB, Genesect wont have the ability to wear down even offensive Heatran variants (granted you can simply U-turn).
Thus, remove the Bug Buzz slash on Thunderbolt. It's indispensable for its revenge-killing / volt-turning roles, imo.
AC mention that Thunder can be used instead of Tbolt on Rain teams. Of course Genesect would also drop Flamethrower for Bug Buzz / Iron Head / etc
Remove the Giga Drain AC mention - weak power with shit coverage is not worth a moveslot. Hell, Psychic or Flash Cannon is more useful.
I would actually AC mention Iron Head / Zen Headbutt for a better way to check Terrakion / Virizion / Keldeo. Terrakion with sand's SpD boost results in a +1 Atk Download boost, just enough for Iron Head to OHKO; Iron Head does a solid 60%+ to Virizion as well. Zen Headbutt is nice for inflicting 80+% to Virizion and 60+% to Keldeo after CM.
[Rock Polish]
Modest > Timid. It's sufficiently fast with max Spe, and it would really want as much special power it can get after it sets up Rock Polish.
Since you mentioned Rain, mine as well mention Thunder for another powerful coverage move.
as Omicron has suggested, AC mention Focus Sash
[Choice Band]
Scarf Landorus / Scarf Mienshao is a nice Volt-Turn partner alongside Rotom-W, since it can take over Genesect's usual revenge-killing role.
[Other Options]
Techno Blast @ Dousing Drive & Thunder provides some powerful coverage moves to go along with Bug Buzz in Rain. Techno Blast is probably better than HP Water when Genesect does not want LO recoils / want to bluff choiced against the REALLY inattentive opponents.
[Checks and Counters]
Kind of wimpy, needs more muscle.
Provide good U-turn absorbers - Gliscor, Landorus-T, and Landorus have relatively good bulk and can switch in on mostly anything not named a +1 Flamethrower outside of Rain or Ice Beam.
Jellicent & Tentacruel can switch into any move not named Thunder(bolt).
Anti- Volt-Turn mons in general are good to mention here. Unfortunately, Genesect just made countering Volt-Turns even more of a nuisance x_x;; As previously stated, Jellicent fits this role imo. Also physically-defensive CM + Reflect Latias can soak up most hits from Volt-Turners, imo.
Not only Magnezone, but now Gothitelle (and by extension Wobbuffet) can trap and kill Genesect with shadow tag.
Also list some specially defensive mons to deal with Rock Polish Genesect (primarily Chansey / Blissey, Gastrodon, Jirachi in Rain).
