The Vessel Knight

Whenever The Vessel Knight enters the battle-
field or attacks, choose a kind of counter at ran-
dom that The Vessel Knight doesn't have on it
from among first strike, flying, lifelink, vigilance
and +1/+1. Put a counter of that kind on it.
When The Vessel Knight dies, exile it and target
opponent creates a 1/1 black Spirit creature token
with flying and "When this leaves the battlefield,
return The Vessel Knight from exile to the battle-
field under its owner's control".
