Forum:Different Sleeves in Tournament?

I'm attending an (unofficial casual) tournament in a few weeks with some friends. Because they don't have many copies of one type of sleeve, they are using at least 2 differently coloured types of sleeves for the main deck. (Example, red and blue sleeves in the same main deck)

If this was an official tournament, what will happen, and if a penalty is issued, what type of penalty will be issued?

Furthermore, in an official tournament, is it okay to have your main deck and extra deck in different sleeves? --HybridDragoness 08:03, June 18, 2010 (UTC)
