I've played this game over and over and never remember needing to find my rival in Mt. Coronet. If you're in the part where Prof. Rowan tells you that you should check on your rival, head up to Snowpoint city. Go thorugh Mt. Coronet and you should find yourself in snowy route 216 when you exit. Sorry if this doesn't answer your question, but I know for a fact that you never have to find your rival in Mt. Coronet.
You can get clefairy in 2 ways: 1. First you need a ditto and a cleffable. Then you put them at the day care. After a while of walking around, there will be an egg. When it hatches it will be a cleffa. You can level it up until it is a clefairy. 2. You can trade clefairy from Fire Red or Leaf Green onto emerald.
If you're playing Diamond, the Pokemon in Mt. Coronet should be Dialga. You have to get the 7th badge before you are able to get to the top of Mt. Coronet where Dialga is though.
you get giratina
The dawn stone can be found in the fog in mt coronet but watch out evil lurks through it muahahahaahaha jk have fun subscribe
Mt. Coronet
yes your rival will heal your Pokemon before you fight Cyrus.
You have to go to the top of mt conoret, where you'll have a battle with your rival against commander Mars and Jupiter. After that you'll go to the distortion world where you have to beat Cyrus and fight Gratina. Once all that is completed, team Galactic will be gone from mt Coronet.
