Franklin, Rocket Scientist

{2}{t}If you do not control a Rocket artifact,
create a 0/0 artifact creature Rocket with,
"This artifact gets +1/+1 for each charge
counter on it. This artifact is not a creature
unless it has 4 charge counters. Flying."
If you do control a Rocket artifact put a
charge counter onto a target Rocket.
