Imagine this: A guy at your local tournament crushes everyone with his
mono-Fire deck. Since all of the people at the tournament want to avoid that
next time, they all make water decks. This makes even battles of water vs.
water. Here's what you can do to give yourself a considerable edge.

Out guess the metagame.

Since you know that everyone will use water next time to beat the killer fire
decks, if you think a step ahead of them, you should make an electric deck to
stomp them. When they make fighting decks to smash you, make a grass/psy
deck. By thinking ahead of your opponents, you can keep the edge in your
corner. Be careful, though, because after using this trick several times,
your opponents will get smarter, and try this trick on you. You better be
prepared.
