i Think that game us Amazing but there is Now the need of a big change. i Think of 2 possibility: 1) pvp Real time 2) team composed of 5 cards instead of 4.
Real-time PVP will probably never happen simply because going first is a huge advantage, and you could never make it fair.
More units on a team could be interesting, but I can’t imagine they’d ever re-do the entire UI as would be necessary. Could be fun, though!
PvP in real time? Not a very good idea since there are players all over the globe and while one part of the players are awake the other part is asleep ….
PvP in real time is an evident idea, and it was already mentioned earlier. But to grant such opportunity to players is difficult. Moreover, I doubt that publishers will allow to add it to the game.
