This sounds black to me. :)

the name or the effect? or both? :P

The effect. It's almost sacrificing a creature to kill another one. So Bone Splinters.

hmm. i think it feels pretty white to me, but i'm open to suggestions.

These issues, especially where is white's removal supposed to be, are very vague, so it depends on you.

The card really wants to be played with Blinking Spirit-type cards, that's for sure. I'd be wary of the flicker effects in this cube, but I guess the end result is just a removal spell for cheap.

Alright, point taken
