I'm doing a ''1st Evo'' run, my team for the first round of the E4 was:
-Clefairy <-this guys DESTROYED Lance
-Moltres <-Ik, it's kind of cheating but I choose the bird with the worst typing compatibility with the E4
After I gained acess to the 7th Island I rushed there to get a Larvitar, and so my team was complete. Now I finally caught Mewtwo and Raikou, as well as the other birds, and started grinding for the second round of the E4 which...... is not going well, I've been practically going up against Lorelei and defeating 4 of her pokemons before being defeated and my highest level at the moment is Moltres at 63 while the lowest are both Nidoran and Larvitar at 60. I'm starting to think it would be better to grind on Mewtwo's cave sincerely....
