Vigilance
Whenever Vhailor, Eyes of Justice becomes
blocked, put a -1/-1 counter on each blocking
creature, then Vhailor, Eyes of Justice gains
+X/+0 until the beginning of the next end step
where X is the greatest toughness among
blocking creatures.
Whenever a creature an opponent controls
would die, instead exile it.
