Stain

Haste, First strike, Fear
Bloodcurdle—
Whenever Stain deals combat damage to a
non-artifact creature, tap it. It doesn't untap
during it's controllers next untap step.
Both this sham-filled society... and the criminals who
wield their power in the name of petty mischief... are
targets of my purge... All for the sake of a better
society.. —Stain
