King Cerberus

Vigilance, Trample

Whenever King Cerberus attacks, put a +1/+1 counter on it.
If King Cerberus has three or more +1/+1 counters, tap target creature an opponent controls at the beginning of combat.

If King Cerberus has four or more +1/+1 counters, when it attacks, deal 4 damage to each opponent’s creatures.

When King Cerberus dies, return it to the battlefield transformed as an Equipment.
