Pack Child

Burden Bearer — When Pack Child enters the battlefield, you may attach any number of Equipment cards and/or Auras from your hand to it. For each
Aura or Equipment attached this way, create a 1/1
green Human creature token.

Overburdened Strength - {1} {g}, {t}: Put a +1/+1
counter on Pack Child for each Equipment or Aura attached to it. If Pack Child is equipped with three
or more Equipment, it gains trample until end of
turn.
