As expected, cylix is hot trash, not even comparable to Navigator's Compass.
A lunchtime draft of the cube in it's current form (sans Zuran Orb) went very well. Much faster, more conclusive games. Decks were Blue Red mill vs Black White aggro/burn.
One critique was that Unsummon might be too good... or at least requires more 1 mana instant removal exist in the environment. Reason being that on the draw, a blocker doesn't save you against a player with a creature and Unsummon. More thought required anyway.
