Brave Frontier

The Brave Frontier deck has 172 cards. 132 of these are Pokémon: 22 Fire, 22 Water, 22 Electric, 22 Grass, 22 Dark, 22 Fairy. However, an actual deck should only have 44: all of 2 types. This allows for customization, where you can make 15 different decks just by switching types. Then there are 40 Trainer cards but you should pick no more than 22. There's billions more for you, just by switching around Trainer cards, making a total of 1.7 trillion combinations. Assuming you use 22 Trainer cards no matter what, of course.
