Glintstone Dragon, Adula

Flying

Glintstone Dragon, Adula has hexproof as long as it's untapped.
Whenever Adula deals combat damage to a player, look at the top three cards of your library. Put one of them into your hand and the rest on the bottom of your library in
any order.

"Adula, a devourer of sorcerers, was bested by Ranni and subsequently swore a knightly oath to her Dark Moon."
