I think they should make a set with every Pokemon in it. They could also chuck in a few 4th gen pokemon. Nun of the Pokemon would be delta species but some should hav sum intrestin types. For instance a water Lugia. Lugia was called a water Pokemon in Pokémon 2000. Hopefuly if a new format is created for the 4th gen then they could redo some of the types. For instance dark could be classified as psychic and flying could be a whole new type!!!
