[Builder] Cube/large deck support

{"ops":[{"insert":"I only recently started using the site in the last few months. I only play and build commander decks and cubes. \n\nThis added support would be of great help to me. From the commander perspective when I first start building a deck I often add 200+ cards to a list before I start refining the deck list down to the final 100. At which points its not uncommon for me to have a LARGE maybe board as well. Another use case is that I have decks with niche focuses where I use the maybe board as a way to keep a list of card that support the overall deck. Admittedly this could be a card package but I haven't dabbled with that feature yet.\n\nAs for supporting lists large enough to be a cube this would be a huge boon, Archidekt's unique way of organizing cards and displaying information makes it a more useful tool to me when it comes to maintaining and building a cube. Cube Cobra is great for when it comes to maintaining an already established list, and collecting draft data, and all the other stuff cube managers need, but I find the list management part of Archidekt more useful.\n"}]}

{"ops":[{"insert":"I'm actually using it for a Cube as well at the moment and on mobile as well. It would be a great boon performance wise for me to use Archidekt for Cube with more ease. It totally gets my vote.\n"}]}

{"ops":[{"insert":"Being able to set rules with syntax searches would be an incredible feature! So just like with commander when you violate the rule it highlights it red. You could add a rule like every card has to be mythic and it would highlight the card if it hit a failure\n"}]}

{"ops":[{"insert":"Yes, I run into this slow down on most of my decks because I like to list alternative options to cards: whether that is because of budget, style of play, or power level.\n"}]}

{"ops":[{"insert":"having large lists not tank performance would be nice for some of the larger conglomeration lists I have that I use for deckbuilding..\n"}]}

{"ops":[{"insert":"I would love this feature!\n"}]}

{"ops":[{"insert":"Yes i'd love this\n"}]}

{"ops":[{"insert":"Additional potential use: shopping list\n"}]}
