Does anyone thought about a multiplayer option? The game is only for 1vs1 but it would be awesome if you could play 2vs2 or all against all with some players.
EDIT: Lets say it is possible. The main difficoult here is: who does my creatures attack? So the first thing to do is to select your current opponent each turn. So if one is heavily protected you could attack the other one.
The spells or effects that affect "all creatures" will still deal with all player's creatures. On the spells or effects that target a player you will have to decide wich opponent is your target.
If there is anything else that matters for this option, just comment it.
