I thought it would be convenient to be able to organize your decks in other ways than just “Starred” go-to deck, then alphabetical.
One of the main ways I would like is manual ordering. Perhaps duelists would want to organize them by favorites, usage, or viability. Maybe a tag for each of your decks saying “competitive” or “casual” would be helpful, too. Color-indicated so we can quickly identify our viable selection depending on if we’re playing with friends or on ranked mode. Tags for decks using only TCG cards and unreleased-in-the-west OCG cards would be great.
Another really convenient filter would be by price! I do not care to suffer through clicking into all of my saved decks to find out the price, and then somehow ranking them cheapest to most expensive without the costs of all of them on the screen at once. You know how the deck name is on the bottom and the deck master’s picture is in the middle? You could put the price on top. Or at the very least be able to hover over your decks for a quick price popup, next to the space where the deck list is. That takes up such a giant chunk of that area anyway. It should be reduced down into a small expandable tab. I don’t know how the current pricing works, but you should be able to sort the pricing, itself, as well. I’d personally want only Near Mint, and be able to select the set and rarity all boiled down into the cheapest buys on TCGPlayer (or trollandtoad, cardmarket, whatever else different regions use.) Obviously, this part of the implementation would take more time, but it would be extremely helpful in picking out decks to get next IRL.
There are probably other ways to filter our deck page, too. I’m down for anything that makes that particular area of Omega more handy.
