"Curser" Build Suggestion

[Brom the Obnoxiously Awesome]

So, I've noticed a lot of different kinds of players and characters within my local PFS community.
I've seen Tanks, Front-Line Fighters (who aren't always Fighters), some Nukers, and a LOT of Healers/ Supporters. However, in an attempt to be useful at my table, I have thought up a great idea for a build- a "curser"

The whole point of this build would be like the opposite of a healer/supporter. His main goal in combat is to completely shut down his opponent, making their dice rolls AWFUL. This gives your team the edge and takes away some of the work that your supporters are having to do.
I was thinking a witch or an oracle would be good for this (I'm leaning towards witch, though).

So First: How do you suggest I carry out this build? Which race, class, feats, etc. I've realized that most of you are better at min/maxing and strategy than me, and that's good.

Second: Do you think a build like this is even viable?

Go all out guys. Don't be afraid to technical, but I'll let you know that the only resources I have available are; The Core Rulebook, The Advanced Players Guide, UC, UM, ARG, Bestiary 1, and I sadly don't have any boons. I can always get on the Player Reference Doc, though, so go ahead and go nuts. Please don't fry my brain though ;)

Okay, thanks guys!

Witch. Witch does this so hard.

It is insanely viable.

Witch.

Evil Eye Hex(works 1 round even if they save, no limit/day). Misfortune Hex. Cackle.

If they're mind immune, no evil eye.

Witch is the best for this, although a sorcerer dip is worth it if you can swing an 11 Cha with your points for the bloodline abilities, and Dual Cursed oracle is like a free misfortune hex(no save) that you can use after the roll.

Crossblooded Undead and Serpentine, Now Corporeal Undead that were once humanoids, Beasts, Magical Beasts, and monstrous Humanoids are all treated as humanoids who share a language for your spells.

Dual Cursed Oracle (Take the Misfortune Revelation)Take Blackened, Legalistic (if you are lawful minded), haunted for curses (remember, half non-oracle levels count towards the curse levels) and take the Sidestep secret revelation for cha to ac and reflex, making you Int/Cha all the way.

Half-Elf is good, take the racial alt that gets you +2 will saves and the elven FCB for Witch of spells known, Human gets the extra feat for an extra hex, but if you go Aasimar Peri-blooded you get int/cha which is awesome for the combo either way, and taking Scion of Humanity lets you take the human FCB for extra known spells.

Takes a bit to get into, but Dual Cursed Oracle 1/Crossblooded Sorc 1/Witch 10

Str 7 Dex 10 Con 13 Int 19 Wis 8 Cha 18 (Aasimar)
Str 7 Dex 10 Con 13 Int 19 Wis 8 Cha 16 (H-Elf or Human)

Increase Int and con at 4/8.

If you only do sorc you can dial the Cha back to 12 and fix dex to 15, which means int/dex for increases at 4/8.
If you take the oracle level at all, take it first and get the 8hp, and take the misfortune revelation and extra revelation Sidestep Secret.

Now, you can use all the person spells on humanoid undead, beasts, magical beasts, and monstrous humanoids without having to memorize the "monster" higher level versions. You have an immediate "no, you don't confirm crit" useable 1/enemy, or pretty much a guaranteed fail to a misfortune hex saving throw.

You never see the major hexes in play, but you will shut down pretty much anything you come across up to level 11 so... meh.

Another option is of course the Hexcrafter Magus. Adds all [curse] spells to spell list and gains witch hexes (albeit slower). Can get arcana that allows spell striking curse spells. Not as awesome as a witch, but good action economy, and somewhat more durable considering that most low level hexes are 30ft range. And as a backup you can always swipe enemies with a sword.

As far as build either elf or half-elf for FCB arcanas which means more hexes. If you so choose you can also go the rime spell rout which is fairly strong with frostbite, frigid touch etc.
