Rudolph the Red-Nosed Reindeer

When Rudolph the Red-Nosed Reindeer enters
the battlefield, look at the top three cards of
your library. You may reveal an instant or
sorcery card from among them and put it in
your hand. Put the rest on the bottom of your
library in any order.
Rudolph with your nose so bright,
Won't you guide my sleigh tonight.
