My experience:
Super fast sealed format, saw a lot of RW ally aggro, WB flyer "aggro", Gx beatdown aggro, and one huge mana ramp deck. Went 4-0 with a bunch of 2 power 2 drops, a few fliers, and like 5 pieces of removal.
Common blue land that days creature doesn't untap is good, ran it in a mardu deck for several games, probably should have started mainboard all night.
Endless one rules sealed, who knows if its good enough.
Awaken cards all impressed.
4BB exile creature and land - very good when you hit a manland, good spell land, and a creature. Could be good enough in the right cube
