The usual strategies involving traps include things like changing attributes to get the best possible bonus from a character gate card or to change your attribute to match your opponent's, thus nullifying the regular gate bonus (Because you get the same one).There arer more complicated strategies using cards like this:
Now this card is risky to play in Pyrus decks because odds are you won't get the bonus and there's a chance it can go wrong in a Haos or Darkus deck if your opponent uses Pyrus.Here's where the trap comes in. Say you play Darkus and your opponent throws a more powerful Darkus bakugan out there. Well, just use your trap to change to Pyrus and net a huge bonus! If your opponent uses a Pyrus bakugan to try and nab the bonus, change to something other than Haos, Darkus, or Pyrus and shaft them with the +0 gate bonus!Traps may seem kinda useless at first, but they can be useful.
