There's some promise here, particularly in the UI. I would have loved to see the cards flip and dance around more ala Hearthstone. I can also see some potential for synergies, but that's kind of limited without initial deckbuilding. The art and music are excellent and the premise is solid enough. I would have loved to see the theme expanded on more than just "Hades doesn't die." Since Hades is the God of the dead, maybe once you die you're allowed to customize your deck with ANY card that was lost in the last round? Would be a great way to get back at my opponents and the massive 9-powered creatures they've got! But overall, a nice job with lots of potential.
