I also more recently sleeved a few of the cards - the monster and character combat decks, and the character ability cards (enough sleeves to swap cards in and out, not obviously enough for every possible card) - and I also recommend that because shuffling and general feel of the cards is just amazing, plus it keeps those frequently shuffled decks in good shape.
