Tyr's Blessing

Enchant Dragon creature
Whenever enchanted creature attacks, reveal
cards from the top of your library until you
reveal a Dragon creature card. You may put that
card onto the battlefield. If you don't, put it into
your hand. Put the rest on the bottom of your
library in a random order.
I have watched you. I have watched the others. I see
much potential in you, in these friends of yours
