I think that Bulbasaur is a GREAT common basic. Look at his only move- LEECH SEED! It costs two energies, I know. And, he only has 40 HP. But, he is the only pokemon in the game with the power to actually regenerate himself! Onix couldn't kill him, and either could dratini.Diglett would need an extra energy, and so would squirtle or seel. Bulbasaur is an almost immune pokemon to anything that does 10 damage, and I myself think thats a pretty cool fact!
