Oh, I can answer that! I have lots of Fairy types, and they're really, really tough! They're totally immune to Dragon-type attacks, and they make even the strongest and scariest Fighting types and Dark types look like they're easy pickings! They can't do much against Poison-types, though, or Steel-types. ...Oh, but to be fair, those types are more suited for defense than offense, so it's hard to take them down by using their weaknesses!
