The latest feature I've added is the ability to play in teams. You can do any combination, so 2 v 2, 3 v 1 or 2 v 1 v 1. Any combination of human/AI is allowed. The fog of war is shared between teammates, so you can see what they are doing. You can also peek on their inventories and spells.
Hopefully it will be out within a couple of weeks.
This has got very complicated but I think I'm getting close to finishing it. I needed to recreate all the multiplayer and battle user interface in the main menu to handle the selection of teams and so on. Plus the server has to handle who is on what team, and there are various in-game changes to be able to communicate with team mates and to visualise team membership and so on.
I've made it so Magic cubes are per-team, and collecting one will share the mana with your team mates. So on a team of two, there will be double the number of magic cubes, but each one will give half the mana.
OK, this update is now rolling out on all versions. There were significant changes made to get this update working. It took a lot of work, so I hope people enjoy it. Please be sure to report any bugs. I'm relying on the regular players to do this!
