My tips are about the the two strongest type not including metle and dark. the to strongest types i think are fire and water. You can beat almost anything with them. If your opponent is useing electric pokemon and your using water switch it and bring out a fire pokemon because electrics weakness is fire.When your using a fire pokemon and you opponent is using a water pokemon switch and take out a water pokemon since water isnt waters  weakness and you still have the advantage of winning.So fire beats electric, grass,flying,fighting,and psy.Water beats fire,psy,flying,rock,fighting.So fire and water make a good deck this deck can beat about anything that it comes up agenst it. I highly reccomend this deck.

If you need information on weaknesses contact me at paintstriper@charter.net i would be more than happy to battle somebody.
