I think I missed Sphinx of Forgotten Lore: 2UU 3/3 mythic with flash, flying. When it attacks a target instant or sorcery in its controller's graveyard gains flashback for its mana cost until end of turn. I had it on my list but I don't remember talking about it. Its actually pretty dangerous as a medium flier that can eat 2/3 and smaller creatures in combat. It also represents a potential big swing in the game if it comes out at the end of your turn and gets to attack and flashback a spell before you can interact with it.
