Lots of the decks that win tournaments are decks that are constantly used and too many people use them.
That is why I like to use decks that are different than all the rest.
I will use a deck that either nobody uses or I will use a deck that is quite common but make a lot of changes to it. Sometimes the decks that I use surprise people because nobody ever uses that deck.
At almost every tournament I go to I use a different deck. It is good to have variety because people won’t be expecting some decks and lose because of it.If I manage to raise enough money to go to Hawaii I already know what deck I would like to use and might use that deck.
