The best signs are here
Raikou, Entei, Suicune, Latios/Latias, Ho-Oh, Lugia, Moltres, Articuno, Zapdos, Garchomp, Hitmontop, Metagross, Celebi, Feraligatr, Buizel, Typhlosion, Meganium, and MEWTWO.
You ride Raikou to jump over chasms, Entei to blow up rocks, and Suicune to ride on water.
Use Latios/Latias to fly.
Ho-Oh, Lugia, Moltres, Articuno, and Zapdos will rematch you at the 3 Mountains, or the seas.
Every other one is for your friendship.
Do not be dissapointed if Garchomp, Metagross,Celebi, Mewtwo,Meganium, Feraligatr, or Typhlosion do not rock in the field.
OK, be dissapointed,
