(No flames, please.)

Warlock might work. Eldritch Blast for the ranged attack. Eldritch Glaive for the in-close. Come up with some nifty moom-themed invocations. Invisibility for flanking. Maybe pick up a couple Rogue levels for sneak attack. Sneak attack eldritch glaive large kopesh sounds nasty enough.

Aside: It looks like a kopesh, not a sickle, nor scythe. IMO
