[Feature request] Set rotation warning

I was wondering what people felt about having a sort of set rotation warning in the cards list of a deck, possibly turning the table cell yellow/orange/red or whatever depending on when that card is about to rotate out of each tournament type. Or, where it says, "This is a complete  Standard deck." it could instead say, "This is a complete  Standard deck (until October 2012)"

Just a suggestion. Thanks.
