Alatreon, King Tyrant

Flying, Trample
Eminence- At the beginning of your upkeep if Alatreon is in your command zone or on the battlefield make a 2/2 wyvern creature token that is all colors.
When Alatreon enters the battlefield look at the top 5 cards of your library, you may reveal any wyvern/dragons from among them and put the into play.
