Let builder make a unique wooden horse,that works like barbarian king, I mean it never be destroyed or there is nothing like that. But this wooden horse as you can guess is related to Troy story, so it has space for troops tu get in. But it cannot damage and its space should be limited for example for its first level it can have 5 barbars or 5 archers and if you upgrade it it will have larger space but not for heavy troops like giants or king. It will be immune against tesla because it has been built by wood but mortars will damage it 2X. So players can make it and attack others and save their troops from opponents defences untill this wooden horse damaged. I think it will be a good idea to let it at high upgrade level to shoot arrows by archers in it and there is possibility to make it stronger. For first level it will be good to have 2000 hitpoint.
