What happens when you max Mastery in Platinum?

With the release of Aether Revolt it's now mathematically possible to master the 1k points in each of the Platinum colors. Though the overhead margin isn't high--Ranges from 75 to 137 points depending on color.

Is anyone close? What happens then, mystery new tier, or maybe the game just crashes?

Interesting question. My highest is 727 in white (918/1040 cards mastered), so I figured I wouldn't hit it until Amonkhet at the earliest.

It would be funny if you get resetted back to Bronze tier.
