Double Sleeving! AKA KEN TIME!!!

OK, is double-sleeving illegal?

13. Card Sleeves
All types of card sleeves are permitted in tournaments, with the following exceptions:
• All of the sleeves on the deck must be identical in every way.
• The sleeves must not obstruct the view of the card face in any way.
• Each card may only be in one sleeve. (Cards may not be double-sleeved.)
If a player chooses to use card sleeves, the sleeves must be from the same manufacturer, be the same color, have the same length, and have the same amount of wear. Players should replace sleeves frequently to avoid worn or marked sleeves. Large plastic top-loading card protectors may not be used in tournaments, as they disrupt the flow of play.
Before sleeving their cards, players should always shuffle both their deck and the pack of card sleeves. This will help prevent noticeable marking patterns in the event that the sleeves have any kind of factory markings.
All sleeves must be in clean condition and be unmarked. A card sleeve is considered an extension of the card. If a sleeve is marked, the whole card will be considered marked, which will result in a tournament penalty.

I don't think it's a problem around here though.
