Two New Legendary with interesting abilities and as expected a Keyrune for Dimir.

Obzedat, Ghost Council

This guy might make it in a EDH/Commander deck, combos well with other Enter the battlefield effect.

A good mill strategy and you get to pick your opponents best creatures that you mill in his graveyard. I think a brew with Jace Memory adept and Duskmantle Guildmage is in the mist.

Dimir Keyrune

Keyrune mana fix or an unblockable creature, this ones obviously great for limited.
