Scizorliscious said:And here's why that's an awful idea:
1) It gets confusing. 17 types? How are you to remember which card is of which type? It would make deck-building a disaster.
2) With anywhere around an equal number of cards for each type, there would be no combinations. And anything close to a good combination would ruin the format by being OP.
3) There would be not enough cards of each type to rely on countering any one type.
4) There isn't enough compatibility. Decks usually only work with very few types of energy - 17 types would make it really tough.
