Ben Kenobi, Mysterious Hermit

Vigilance
Whenever Ben Kenobi attacks, reveal the top
card of your library. If it's an instant or sorcery
card, put it in your graveyard and you gain 4 life.
If it's a creature card, put it in your hand and you
gain 1 life.
Whenever a creature enters the battlefield under
your control, that creature gets +0+1 until your
next turn.
