An undead elf druid/shaman. If you know Magic, think
Golgari. Something Jarad-ish, decomposing if not quite so rotten that he's
missing parts of his face or something. Still, clearly (un)dead. If the missing facial feature makes him kickass, go ahead.
X Elf, sentient undead
X Earthy clothing in browns and dark greens, moss, etc.
Shoulder-length white/grey hair
Pallid, gray skin. Zombie veins or other features of decomposition.
Vines?
Cloak
If you manage to get that odd, somehow regal feeling present in Jarad and occasionally found in vampires and stuff it in a stick figure, you're amazing.
For any magic effect things the dark purple in Jarad cards is superb.
