Rivals of Ixalan: mechanics

Prerelease of Rivals of Ixalan starts on January, 13. This time there are few returning mechanics, such as: enrage, explore, raid, transform and double-faced cards. We will get only one totally new mechanic:

• Ascend - if you control ten or more permanents, you get the city's blessing for the rest of the game. The city's blessing isn't a permanent or emblem, and nothing can destroy it or otherwise interact with it. When you have the city's blessing, you gain a significant advantage depending on the spell you played. Both permanents and spells can have ascend. If a spell has ascend, you get the city's blessing as part of the spell's resolution if you control ten or more permanents. If a permanent has ascend, you get the city's blessing immediately once you control ten or more permanents: this is a special action that doesn't use the stack and cannot be responded to. Ascend always looks at the current game state, not the past, and all the time checks how many pernaments you have.
