Let me tell you about this proposal, this proposal is about a Colosseum. This could be a build-able building that is about 1 of your best men in your army vs another persons best men on his army. On how to get a best man in the army is by training him different moves and techniques in the same building you built him on. Say for example a warrior could get trained in the warriors barracks, he gets trained for doing moves and techniques in the same building but it will cost some resources.
Rules The moves and techniques can only be used on the Colosseum no where else, the man you train will be a regular soldier in the battlefield but not in the Colosseum. He will need resources in order to be more stronger and more efficient. You could only battle people in your age period.
This is kind of like a process of a great building but you could use this unit in order to win prizes at the Colosseum
This is how the proposal works, tell me what you think about it
