Ogenfell, the Teller

Whenever you cast a legendary spell, scry 3.
At the beginning of your upkeep, put the bottom card of your library into your graveyard. If it was legendary, instead put it on top of your library. If it was legendary and green, instead put it into your hand.
Whenever you scry for your third time in a turn, add {g}{g}{g} and gain 3 life.
