The Glus

Delve
When The Glus enters the battlefield, exile any
number of cards from your graveyard, The Glus
gains +1/+1 for each card exiled in this way.
{t}Tap target creature, it doesn't untap until
The Glus is removed from the battlefield.
Where Enna sleeps, the sea-worm creeps,
And spins its webs of bone-white stone.
-Toran Folk Song
