Re: 150 help please
To get the Nat'l Dex, seeing all 150 is needed. Manaphy is unnecessary.
Beat the Elite Four, and the other versions legend can be seen from Celestic Town.
I can trade you an egg moved 115, male Riolu now if you like.
As for 65, maybe that too.
And the Nat'l Pokedex is only needed for Pokedex reading. I had a Venusaur when I fought Crasher Wake...
