Ok, so here's an example of what you do. I'll describe a Pokemon: Its is a Dark/Ghost type, is attached to a rock and the Sinnoh's champion has it. You would answer Spiritomb then describe another one like I did. (No Isshu pokemon, please)
It is a Dragon/Steel, only catch it in the Sinnoh, Legendary.
If idiots were planes, this place would be an airport.
