Namielle, the Blinding Abyss

Hexproof
Whenever Namielle enters the battlefield or
attacks, you may discard up to 2 cards. If you do,
draw that many cards. When a land card is
discarded this way, add {g}, {u}, or {r}.
{u}{u}: Reveal the top card of your library. If it's a
land card, you may put it into your hand.
Otherwise, put it on the bottom of your
library.
