Lord Voldemort

Whenever another creature dies, you may put a horcrux counter on target artifact you control
without a horcrux counter on it. If you do, you
lose X life and draw X cards, where X is the
number of permanents you control with horcrux counters on them.
As long as you control a permanent with a
horcrux counter on it, Lord Voldemort has
Hexproof and Indestructible.
