How Do I Make a Team Have a Limited Number Of Players?

Hey, I'm making a game which has three teams, Mortals, Mortal Heroes, and Gods. I want to make it so that the Gods team can only have one player on it at a time and so that when the God dies he becomes a mortal (joins the Mortals team.) The Mortals and Mortal Heroes teams should not have a team limit and when they die they should stay on the same team, I just want these rules to apply to the one player on the Gods team. The team colors are Lapis for the Gods, Really Red for the Mortal Heroes, and New Yeller for the Mortals, in case you need any of that information to make this work. Could anyone help me figure out how to do this? Thanks, and comment below or message me on Roblox if you have any questions or if you need any more information to answer this. Thanks, Skyraider5

Highly recommend you don't copy and paste, however I did put it into context for you. If you have any questions please reply and I will help asap.

local teamz = {
	['God'] = 1,
	['Normal'] = 16
}

local teams = game:GetService('Teams')
local gods = Instance.new('Team', teams)
local normal = Instance.new('Team', teams)
gods.Name = 'God'
gods.TeamColor = BrickColor.new('Bright Red')
normal.Name = 'Normal'

local function getamount(str)
	local amount = 0
	for k,v in next, game:GetService('Players'):GetPlayers()do
		if v.Team == teams[str] then
			amount = amount + 1
		end
	end
	return amount
end

game:GetService('Players').PlayerAdded:connect(function(p)
	p.Team = normal
	local lteam = p.Team
	p:GetPropertyChangedSignal('Team'):connect(function()
		table.foreach(teamz, function(a,b)
			print(p.Team == teams[a], getamount(a) - 1 < b)
			if p.Team == teams[a] and getamount(a) - 1 < b then
				print'you can change teams!'
				return
			elseif p.Team == teams[a] then
				print'sorry, this team is full!'
				p.Team = lteam
			end
		end)
	end)
end)
