Grass / Ghost
Defensively
Immunities: Normal, Fighting
Resistances: Water, Electric, Grass, Ground
Weaknesses: Dark, Flying, Ice, Ghost, Bug
SmashCAP 2 would resist / be immune to all the Returns, Close Combats, Surfs, Thunderbolts, and Earthquakes in the OU metagame. If you ask me those are pretty handy for switching in on Swampert, Gyarados, etc. The weaknesses can be played around. Flying and Bug are fairly uncommon attacking types outside of Togekiss and Scizor. A Ghost-type attacks are typically restrcited to Gengar and Rotom. Neither of whom would enjoy switching in on SmashCAP 2's own Ghost STAB anyways. Dark-type weakness is a problem, as it easily becomes Pursuit-prey for Scizor. Perhaps something could be done to remedy this. But again, SmashCAP is not meant to design perfect Pokemon.
SmashCAP 2 under this typing takes 12% from Stealth Rock and is also immune to Leech Seed.
Offensively (Both STAB accounted)
Supereffective: Water, Rock, Ground, Ghost, Psychic
Not very effective: Fire, Grass, Steel, Bug, Flying, Dragon, Dark
Immune: Normal
Grass isn't all that great for offense, resisted by a ton of types, but the supereffective hits it gathers are still useful. It can nail Vaporeon and Tyranitar for good damage. Ghost STAB scares away Gengar and Rotom, while hurting Celebi pretty badly. The resistances to Grass / Ghost are plentiful, but with Stealth Rock support 3 of these become handicapped.
Yeah, yeah, yeah...Scizor would love this thing, but let's look beyond that. Being Grass / Ghost gives SmashCAP 2 access to all forms of status through Sleep Powder, Stun Spore, Toxic, and Will-o-Wisp. Stun Spore lacks the accuracy of Thunder Wave, but won't be sucked up by Ground-types, or heal Jolteon / Electivire. Since it's part Ghost it can also use Confuse Ray, but that's not really that important.
The reason this could help the screaming Scizor problem is Will-o-Wisp. Scizor really won't enjoy the attack halve all too much. It could remedy if it was a Swords Dance set, but it'll still be taking 12.5 damage each turn.
This is just another idea from me. Criticize / hate / support.
