Blade of the Demented

At the beginning of your upkeep, if Blade of the
Demented is attached to a creature, you may put
a -1/-1 counter on target creature you don't
control. If you do, put a +1/+1 counter on
equipped creature.
When equipped creature dies, you draw X cards
and lose X life, where X is the number of +1/+1
counters on that creature.
