Artifact â Equipment
Whenever a creature dies, put a +1/+1 counter on equipped creature. If equipped creature is a Vampire, put two +1/+1 counters on it instead.
The creature that gets the counters is the one thatâ€™s equipped by Blade of the Bloodchief at the time the ability resolves. It doesnâ€™t matter what creature Blade of the Bloodchief was attached to (if any) when it triggered.
The +1/+1 counters are put on the equipped creature, not Blade of the Bloodchief. If Blade of the Bloodchief is moved to a different creature, the +1/+1 counters will stay where they are.
If the equipped creature itself is put into a graveyard, Blade of the Bloodchiefâ€™s ability will trigger. However, it wonâ€™t do anything when it resolves unless a spell or ability has caused it to become attached to another creature by that time. (Remember that you may activate an equip ability only as a sorcery.)
If the equipped creature and another creature are dealt lethal damage at the same time, the equipped creature will be put into a graveyard before it would receive any counters.
If Blade of the Bloodchief leaves the battlefield before its triggered ability resolves, the counters are put on the creature it was attached to at the time it left the battlefield. If it wasnâ€™t attached to a creature at that time, nothing gets the counters.
Blade of the Bloodchiefâ€™s ability triggers regardless of who controlled the creature and whose graveyard it was put into.
