Norra, The Portalmaster

Flying

When Norra damages a player, reveal cards from the top of your library until you reveal a creature with mana value 3
or less. Put that creature onto the battlefield tapped and the rest on the bottom of your library in a random order.

Level up (When you've cast 6 or more creature from your library, give Norra +1/+1 and "Norra's ability now searches for creatures of mana value, 4, 5, 6, or 7 instead.")
