I like the concept!
I fail to find how to play single player, all I get is multiplayer. As I get to play both games and they're fairly independent it is no big deal, but still.
Suggestions/ideas:
1. Sorting and better overview of your hand.
2. more interactions with the other player(s). For example, add the ability to use the previous players' movement to complete a surrounding attack.
3. Some further development of the day concept. As is, there is little reason to care about how many days you use, making drawing cards until you have all your cards in your hand the usually best choice.
4. Maybe limit the possible amount of draws per month, instead get slightly better cards and make trashing/evolving of cards important, to make the game flow a bit better.
