Today I had a think about how I could improve the control players have over the battles. I came up with the idea of 'power' cards, which would be playable during the automated battle and provide buffs to your units or debuffs to the enemy. The first step towards that was actually adding cards to the game, which I did today. Now you drag your units onto the battlefield from your hand. The idea will be that you gain access to new cards as you win battles.
