The Grand Completion is Achieved
As I suspected, the next set in the Scars of Mirrodin block will be named New Phyrexia as opposed to Mirrodin Pure.
As the preview card indicates, each of the Phyrexian Praetors will be seen in Legendary Creature form and will probably be Mythic Rare. There are also rumours that Karn will be make an appearance in this set. As for Planeswalkers, there is yet to be a Green aligned one for this set as well as a few missing multi-colour walkers.
The final sword of the series will also make an appearance. It will give the equipped creature +2 +2 and protection from Red and from White but its other abilities are yet to be released. Rumours are it will be called 'Sword of War and Peace' or 'Sword of Order and Chaos'.
All Will be One
