Traps are type of item in Shadow Era.
Traps are a special kind of item that can be played face-down (so they are a surprise to the opponent), and activate when a specific action written on the particular trap occurs. In Call of the Crystals, there were only two different traps (Net Trap and Death Trap), and they both had different casting costs, so it was actually possible to tell which had been played despite that they were face-down. In following sets, more traps have been introduced, so it is harder to determine the trap that has been set this way. Traps are currently limited to the Hunter class.
