I have a few questions about my HG-Nuzlocke. My team is currently Croconaw/Scyther/Nidorina/Stantler/Kadabra/Gastly. Now I wonder if it is worth keeping the Gastly, if I can get it to Gengar at lv 25. By level-up it doesn't learn much more than Shadow Ball and Dark Pulse, and it's kinda frail, so I wonder if I should keep it.
Also, I just got my Eevee from Bill, what should I evolve it in, looking at my current team?
