New rule for Shards of Alara Release!

Some of the keen eyed players may have noticed this bit of information floating around on the internet recently...

"Tournament Structure/Format: [for Shards release Sealed]
(basics about building a sealed deck (a tourney deck and three boosters) followed by...) Players must choose one of the five Shards and construct a deck using cards that share the same colors of the Shard chosen."


Once you remove the jargon from it, it states that each player (upon receiving their sealed deck) must choose one of the Shards (3 colour alliances) of Alara and can only play cards represented by those colours.

So no four colour decks, no funny splashes; just do what Wizards tells you to.

I'm personally miffed, however I'd like to know what you folks think. Fun wrinkle, or yet another terrible decision by Wizards?

Post-script: allegedly the release will also feature special "super" lands which tap for 3 different colours of mana related to your shard. No mana screw here, I suppose.

This particular rumour I'll only believe once I see it. (As opposed to the deck building limitations, which Wizards has press-released)
