I could (for better type coverage)
Get an Exeggutor instead of Hypno.
Get Moltres to replace Fearow (I'd use Fearow till then)
My Leaf Green Team would be:
Ninetales
Seaking
Diglett/Graveler/Nidoking or Queen
Pidgeot
The rest, not a clue!
I'd like to (please don't kill me for saying this) use Raticate! I've been wanting to for ages! But if not, OK.
Typhlosion
Nidoking (The best ground type)
Poliwrath
Xatu
Umbreon
Magneton
Can I not have a Crobat instead of Xatu and get a different Pokemon to replace Nidoking? I've been wanting to use Zubat for ages as well!
