[Champion Concept Brainstorming] Komachi, the Soul Reaper

I'm looking to pick up where Xypherous failed when he tried to make "Komachi". His original design was that of a space-manipulation tank, one that had some real impractical OP-ness to it (i.e. a wall that teleported people who walked into it). However, I still want to try and make my own spin on the idea.

To that end, however, I'm gonna need some suggestions on pieces of a kit. I'd like something that is about manipulating an enemy's position, whether to screw up their attack or set up kills for your teammates, though in a different style than Thresh.

Here are abilities I've thought up so far. Everything is subject to change.

P - Deathscythe

Komachi's attacks are periodically enhanced, damaging surrounding enemies for X% of her total attack damage and slowing enemies hit by 30/40/50% for 1.5 seconds. Basic attacks reduce the cooldown by 1 second. 14/12/10 second static cooldown.

Q - Reaper Strike

Komachi's next basic attack has 125 increased range (her natural range would be 175), deals bonus damage, and pulls her target a fixed distance toward her. Resets attack timer. Applies on-hit effects.

W - Earthbound Spirits (tentative name)

Komachi spins her scythe in a circle around her, dealing physical damage to nearby enemies (300 range) and creating a field for 2.5 seconds that slows enemies within it. When the field expires, any enemies still within it are immobilized for a short time.

E - Soul Journey

Komachi fires a skill shot. If it connects with an enemy Champion, it deals magic damage and warps the target back to where it was 2 seconds prior. Long cooldown and has a fairly long wind-up when firing.

Don't freak out at these ideas. They're just prototypes, and you should expect them to change.

EDIT: And here's the obligatory sexy shinigami picture to give you guys some "inspiration". ;) http://api.ning.com/files/zRBhkYpTMVk5PMNVp196ybgcYNCNbhnkx-tCMahQSCgudYWl0HydaWrGKMRjBcZ60PswOK*5kNzLLBzflqBcR6sdgat5O9ij/Konachan.com87042cleavageonozuka_komachipicored_eyesred_hairscytheskirtthighhighstouhouwhite.jpg

EDIT2: Haven't worked on this in a while, but I got an idea for a W skill.
