I had to make this sliver up due to the tails not matching any of the many slivers that exists in the mtg multiverse. Their looks vary, but typically they have two long tails, one arm with a scythe, and a head that resembles an aliens.

Sculpt over a broken cyclops figure with a Sigma 6 head for stronger and better articulation. Used two McFarlane alien resurrection Tails for the tentacles. Also used mystiques leg to complete the arm
