Developers what the hell?!?! How have you created a card game so addictive, so attention grabbing that I can't put it down and all I want to do in my time, not even free time, is play this game. You're clearly wizards, there's no other explanation. I have one thing that can improve it even further....create a "compatible viewing" option for cards that say "gives a buff/debuff to x-card" then show that card to the players and if they own it or not. That'll give them something more to strive to.
