I use one of these cases. I can fit three sleeved decks in it, leader cards, and all my other cards organized by color type and energy cost. Super portable and easy to find and rearranged cards or make changes to decks.
Last time my traveling case (https://www.amazon.com/gp/product/B00VJMDZHS/) easily fit:
Just a suggestion for a deck box if you plan on carrying several decks with you. The smacase h300 is a great case. It holds 720 sleeved cards. I use it to carry 3 commander decks, sleeves for draft, a tiny leader deck, and a 60 card standard deck, and still have room for draft chaff and extra cards from draft or sealed.
Did you know Amazon will donate a portion of every purchase if you shop by going to smile.amazon.com instead? Over $50,000,000 has been raised for charity - all you need to do is change the URL!
