Satabwaah, The Gentlerabbit

When Satabwaah, The Gentlerabbit enters
the battlefield, all opponents put a 0/1 white Gift creature token onto their battlefield.
They have: ``At the beginning of your upkeep,
you gain 1 life.``
Whenever an opponent gain life, you may
put +1/+1 on target creature you control.
Don't worry, there are carrots in the gifts!
