Enshackled Hellkite

Defender, flying
Whenever a creature you don't control dies, put
a +1/+1 counter on Enshackled Hellkite. It loses defender and gains trample as long as it has four
or more +1/+1 counters on it.
At the beginning of your upkeep, if Enshackled Hellkite has trample, it deals 2 damage to each other creature.
