The revealing spell should reveal where all the traps are to the other player for a short period of time somewhere from 5-10 seconds. This spell maybe seem overpowered but even if someone were to know where the traps are they wouldnt be gareented the 3 stars, plus the time would go by so fast that they wouldnt have much time to think or look around. This spell should only be able to be used once and in the very beginning when battle time is count down. This spell should be worth 50,000 elixir and be only avaliable to townhall 9 and 10.
