Greenhilt Trainee

Oracle Text

T: Target creature gets +4/+4 until end of turn. Activate this ability only if Greenhilt Trainee's power is 4 or greater.

Card Rulings

6/1/2011 Once Greenhilt Trainee’s ability is activated, it will resolve as normal even if Greenhilt Trainee’s power is less than 4 at that time (perhaps because an Equipment attached to it was destroyed).
