Ultra Instinct

Hexproof
Instants and sorceries you cast cost
{2}{u}{r}{w} less to cast.
You may look at the top X cards of your library
and put them back in any order at any time.
You may cast the top card of your library if it's a noncreature, nonland card, and you may cast it as though it had flash.
If Ultra Instinct would leave the battlefield,
exile it. Its owner loses the game.
