I love this idea, a sandbox to test bots against with no gain, and how about we make it so we can fool around on it, like make it so we can have as many units as we want, infinite gold and mana, and we can make it so we can control both sides and have control of all units (chaos, order, and elementals) just for the fun of the sandbox, remember its a sandbox not the actual game so we can just test things and sometimes have fun with it.
Their would be two types of this, the sandbox in which you can fool around with infinite units, all kingdoms, and infinite gold/mana, and then there's the testing room where you test strategies with the kingdom type you already have and everything is set to normal except the bot AI, the race of the bot, and the map (you choose the intelligence of the bot, you choose the map played on, you choose the race of the enemy)
But of course you cannot gain points or EC from these.
READ THIS, this is my idea for the sandbox/testing game.
