Random Team Script(Supposed to place you in a random team), would it work?

Would it execute smoothly? It is supposed to change your team to a random one when the server gets to twenty players.

--[[---Thanks to free-model for helping w/reconstruction.
	& please insert the a number value called "Players" into Teams.
	READ:
	1. Insert NumberValue "Value" straight into this script & insert NumberValue "Players" into Teams.
--]]



A = game.Teams:findFirstChild("TeamName")
B = game.Teams:findFirstChild("TeamName")
C = game.Teams:findFirstChild("TeamName")
D = game.Teams:findFirstChild("TeamName")

function Redo()
	wait(5)
end

	if game.Players.NumPlayers = 20 then
		Assign() else
		Redo()
	end

function Assign()
	A.Players.Value = 0
	B.Players.Value = 0
	C.Players.Value = 0
	D.Players.Value = 0
	teamchosen = false 
	player = game.Players:GetChildren()
	for i = 1, #player do 
		print(player[i])
		if A.players.Value == B.players.Value
			if teamchosen == false then
				script.Value.Value = math.random(1,4)
				if script.Value.Value == 1 then
					player[i].TeamColor = A.TeamColor
					teamchosen = true
					A.Players.Value = A.Players.Value +1
				elseif
					script.Value.Value ==2 then
					player[i].TeamColor = B.TeamColor
					teamchosen = true
					A.Players.Value = A.Players.Value +1
				elseif
					script.Value.Value ==3 then
					player[i].TeamColor = C.TeamColor
					teamchosen = true
					A.Players.Value = A.Players.Value +1
				elseif
					script.Value.Value ==4 then
					player[i].TeamColor = D.TeamColor
					teamchosen = true
					A.Players.Value = A.Players.Value +1
				end
			end
		end
	end
end

Will it work?

NO there are problems I took your code and made it nicer, here you go

Teams={"Bloxers","Sky Warriors","Sand Archers","Korblox"}
--Name of teams you can change it
AmountOfPlayersRequired = 20

while true do 
  player = game.Players:GetChildren()
  wait(1)
  if #player >= AmountOfPlayersRequired then --waits until players are above or equal to 20
  Assign()
  break
end end


function Assign()
  players = game.Players:GetChildren()
 for i = 1,#players do 
 ChosenTeam = Teams[math.random(1,#Teams)]
   
   players[i].TeamColor = game.Teams:findFirstChild(ChosenTeam).TeamColor
   end
  end
