I've been looking furiously for some sort of suitcase or softer bag that could hold my entire collection. MTG cards have the same dimensions as LOTR LCG, so official products like the Dragon's Egg would certainly work well for smaller quantieis - they can only hold a few decks at a time.
I think the best bet is to find some aluminium case and acquire or create your own dividers. Has anyone had similar thoughts? Any tips/recommendations?
