Vile-pus Stalker

Deathtouch
{b}, Sacrifice a creature: Regenerate Vile-pus
Stalker (The next time this creature would be destroyed this turn, it isn't. Instead tap it, remove
all damage from it, and remove it from combat.)
It draws in its pray with a beautiful pink flower, only
to dissolve them in necrotic concoction of rotting pus
and boiling stomach acid.
