Karma, Enlightened One

At the beginning your endstep you may reveal cards
from your library until you reveal a
non-permanent card, put that card in your hand,
and place the rest to the bottom of your library in a
random order.

Level up - If you can produce 10 or more mana of
any colour, give Karma +1/+1 and "At the
beginning of your endstep you may cast any
non-permanent cards that entered your graveyard
this turn, for free."
