Neolithid

{t}: Detain target creature as long as Neolithid
remains tapped; you my choose not to untap Neolithid. When the creature is no longer

{b}{b}: Destroy creature detained by Neolithid.
This creature is a slime-covered, ten ta cled worm of dragonlike proportions. Four 25-foot-long tentacles
sprout from its eyeless head, writhing around a lampreylike mouth of nightmarish size. A revolting
mucus trail marks the wake of the horror.
