"The November 2013 Standard arena rotation is now online. On the first Monday of each month, we will be cycling the Standard arena pool. Rather than only having access to the same standard arenas day in and day out, each month we will now feature 26 arenas selected as playable for Standard-level matches.

Newly released arenas will remain exclusive for at least three months, but every other arena is eligible to be included in the cycle."

Standard Map Pool:
Start date: November 4, 2013
End date: December 2, 2013
