Just got Blue, so two questions...

[Kasaioni]

1) How do you swich a pokemons moves?
2)For the newer mew trick, is it the gambler nearest lavender or nearest safferon?

 

[P_S_B]

To switch a Pokemon's moves, press select for the move you want to switch, then press select again for the move you want to switch to.

For the Mew Trick, it's the gambler nearest Saffron.

I know nothing about the newer Mew trick, but I know for a fact that the old one works.

Yes, but you can only do it while in a battle IIRC, just do the above when you're selecting the Pokemon's move.

2)For the newer mew trick, is it the gambler nearest lavender or nearest safferon?

Isn't the Mew Trick with the gambler the older one? 'Cause I thought the newer one involved catching an Abra and using teleport...
I'll have to check the sticky...
