Two creature types have strong enough synergies to show up later in the list, but there arent quite enough in angels, clerics, elves, legends, and vampires to create critical mass in a typal deck, but heres some of the good ones: Bishop of Wings Cordial Vampire Elvish Dreadlord Orah, Skyclave Hierophant Patron of the Vein Ratadrabik of Urborg Skemfar Avenger #19
