Majora's Mask

Whenever a permanent is destroyed during your
turn, place an armageddon token on Majora's
Mask.
{b}{r}, {t}: Remove all armageddon counters from
Majora's Mask and deal damage equal to twice
the number of armageddon counters removed in
this way to any target.
"If it's something that can be stopped, then just try
to stop it!"
