Milhara, Cruel Inquisitor

Whenever you cast a blue creature spell,
you may draw a card, if you do discard a card.
Whenever you cast a green creature spell, you
may search your library for a creature card reveal
it, then shuffle your library and put that card on
top of your library.
(Both abilities trigger if the creature is blue and green)
There is no hiding, he will find all of us.
