Many new troop ideas + spell

Me and my friend are very heavy clash of clans players and we have came up with some great ideas to improve our favourite game. Our spell idea would be an invisibility spell that would cost 80,000 elixir and would last 10-15 seconds and would take 5 hours to make for the amount of the defenders canons archers ect could not see your troops .Our next spell idea was the infiltration spell it would cost 100,000 and take 8 hours to create elixir and you could spawn your troops inside the enemy's base.
