I am very new to the game, started in 2014. 

Playing casually EDH and drafts with my wife. We tend to not mix colors in playing EDH so actually need single cards in our collection. Every extra copy  will be available for trading.

When we play drafts, before we even start drafting we put all the cards in KMC Hyper Mat sleeves to protect them . After playing draft we remove cards from sleeves and store them in the storage boxes. Mythic rare and rare cards are stored in KMC Perfect Fit sleeves and are dual sleeved when playing EDH. That said, most of our cards except our first initial M14 Intro Decks and M14 Deckbuilder toolkit cards are Near Mint(will not list them as Mint because we are handling them)
