Coven Slitherspeaker

Deathtouch
At the beginning of your end step, create X 1/1
black Snake creature tokens with deathtouch,
where X is the number of auras you control
attached to an opponent or permanents your
opponents control.
"Beasts that slink and coil and slither,
from the dark I beckon hither,
make them writhe and make them wither..."
