How so?
High converted mana cost matters cards (I'm betting we get a full Riddle of Lightning cycle in light of the one spoiler), Power/Toughness matters card (Token reanimation spell), and hardcore kill anything removal.
Also, as a Zendikar throwback, Fetch lands (coming back just in time for no shocks, so no Magical Christmasland)
I don't know if I would do it though- too many people consider RoE a perfect draft format, and I don't have any faith in this current group of recreating anything close to it.
