[Trigger] How to make castle to defend for each team

[nhammen]

Hello there.
I think the thread name doesn't explain well since i didnt know how to put it.
So what i need is a trigger that makes 1 Different Hero (i change my mind so i diced to ask for hero instead castle) for each team and enemy for the others .

I need also a upgrade center that has upgrades for the hero(like hp, armor, dmg, etc)

If possible the upgrades to take gold and lumber from all players like if upgrade cost 15 gold 30 lumber so 5 gold and 10 lumber from each team player and if someone doesn't have the resources show some kind of message

Make a unit group with the heroes then just randomly give one to each player. Remove the given hero from the group.

For the upgrade center, create player groups for the teams, make a neutral building, add a tome that costs NOTHING. If someone acquires that item, you check the players in the correct player group. If everyone has the required materials then you can give the upgrade.
