Every game I like to go through with Pokemon I haven't really trained before, and are from that Generation. So, for this I'm going to use all Gen II Pokemon.
I really have no clue what I used in my original Gold, as I honestly didn't play it that much. I'll probably end up playing this more, lol.
1.Totodile -> Croconaw -> Feraligatr
2. HootHoot -> Noctowl
3. Ledyba -> Ledian (too bad it sucks, lol).
Or, if 4th Gen Evos are Pre-E4
Yanma -> Yanmega
4. Slugma -> Magcargo
5. Sunkern -> Sunflora
6. Depending on if they have new evos pre-E4, I'll probably use Misdreavus or Piloswine. If not, probably go with Sudowoodo.
So basically the starter triangle, although not all starters. A bird, a bug, and a random member. A traditional team sort of.
