Enchant creature
Enchanted creature has lifelink and "Whenever a creature dealt damage by enchanted creature dies this turn, gain 3 life."
Role- At the beginning of your endstep, if your life total is less than five, return Glutton's Review from your graveyard to the battlefield.
See Wings of Surveillance. I don't remember if I need to say "attached to target creature." at the end of the Role ability.
