These soon-to-be-legal cards seem aimed at the same high power level as those printed in Commander precons, and include 30 new legendary creatures, one of which was previewed today

The last ability of Clive's Hideaway will allow you to cast both exiled cards without paying their mana costs (assuming you control four or more legendary creatures at that time.)
