Adrastos & Celestial

When you cast Adrastos, create a legendary 3/3
Beast token named Celestial with "Deathtouch, Reach, Vigilance" and "When this creature kills
a creature with less power, it gets a +1/+1
counter."

When Adrastos enters the battlefield or attacks, target creature gets an additional counter of one
kind it has.

"Ours is the strongest"
