The Elite Four don't stand a chance.
They wouldn't stand a chance even if it was just this:
Fire
Anyway, I'm sure they'll change up the wild pokemon, adding
in some hoenn and sinnoh, so I can't really say.
Mine won't really depend on the starter I choose. The only
one that will change is one other pokemon to compliment the
type advantage and stuff. As for the actual line-up, I am unsure.
The pokemon that I am predicting I will catch will be (assuming I
choose Cyndaquil, since it has the best overworld sprite)
Bellsprout>Victreebel, Poliwag>Politoed/wrath, Aerodactyl (from
underground, hopefully)
