I feel I should address the CB Genesect issue, since I'm the QC person who approved it (to which Shurtugal referred). I'm not the world's greatest player and me QC approving CB Genesect does not make it good with no justification.
Firstly, for those of you that haven't looked at the Genesect thread in C&C, the best CB Genesect is not quite the one people are referring to here. For starters, Iron Head is virtually useless, such that it probably isn't even going to appear on the set when it goes on site (assuming it does). It offers practically no coverage over U-turn that will not be covered by Genesect's other moves.
The moveset I actually use is: U-turn / Zen Headbutt / Flamethrower / Ice Beam or Explosion. Yes, Explosion is not a given either. The power of Zen Headbutt is really not to be underestimated. With an attack boost, it has the power to OHKO virtually every Fighting and Poison-type, and frail Fire types like Volcarona and Ninetales. That includes Keldeo, Conkeldurr, Tentacruel, Lucario, Terrakion (you don't need Iron Head, therefore) and Infernape. The last two moves cover steels such as Skarmory, Forretress, Scizor, Ferrothorn, Genesect etc. and Gliscor, Landorus-T, Landorus-I, Dragonite, Salamence etc. Everything that doesn't take a really big chunk of damage from U-turn is well covered except for Heatran.
Bearing that in mind, I should now explain why CB Genesect is a good set. For starters, I'm definitely not saying it's better than Choice Scarf and Expert Belt Genesect, because it isn't. What it is, though, is sufficiently different, and quite clearly viable. It beats Special walls, and really punishes the opponent without you needing to predict (guess) much at all. That U-turn is just absurdly powerful, and you use it virtually all the time. It clearly has numerous advantages over Choice Band Scizor: Speed, power and COVERAGE at the expense of Bullet Punch. Yes, it has a terrible physical movepool, but its coverage absolutely blows Scizor's out of the water. Its only good switchin is, as ever, Heatran. Until Genesect came along I never wished Scizor had Zen Headbutt but I do now.
It's also worth noting that people are deliberately giving Genesect attack boosts. I get attack boosts most of the time, and I'm going to make my opponent pay for that.
Quick attack is also an option for the last slot. I don't know how good it is compared to the other moves, but it should deal significant damage for revenge killing weakened opponents if you get an attack boost.
