As a true trainer, it's a challenge to build an effective team of only one pokemon. To give it the moves and training to cover it's weaknessess, to breed moves into the pokemon that allow it to work well with it's teammates, everting must be considered. Unfortunatly, doing a team of Azelf has it's disadvantages. As a legendary, you cannot give it unique egg moves, and as a one-type pokemon, it has no resistances against types that it's other type is weak to. So, it is even more of a challenge, and one I'm perfectly willing to accept! Now that I have an excess of Meditite from trying to breed one with an adamant nature, I'm considering building a team of them, too.
