Death Watch

Vanishing 3 (This artifact enters the
battlefield with three time counters on it.
At the beginning of your upkeep, remove a
time counter from it. When the last is removed, sacrifice it.)
When Death Watch leaves the battlefield,
if it had no time counters on it, each player
loses 4 life. You create a 5/5 green horror
creature token with trample haste.

"Gentlemen, synchronize your death watches."
