Mad Dog-Prime

Whenever a creature you control with an
overheat counter on it dies, put a +1/+1 counter
on Mad Dog-Prime.
As long as there are four or more +1/+1 counters
on Mad Dog-Prime, Mad Dog-Prime has
Lifelink, First Strike, and Vigilance.
Mad Dog pilots have been known for showering
missiles on opponents before swooping down with a finishing blow from the lasers, much like a
vulture swooping down for carrion.
