Arvad, Weatherlight Smuggler

Deathtouch, Lifelink
At the beginning of your end step, if a creature
died this turn, put X +1/+1 counters where X is
the number of creatures that died this turn on
Arvad.
This also triggers if Arvad is in your graveyard.
As Arvad moves to any zone other than a player's
hand or library, +1/+1 counters remain on.
