It depends on your personal preference. However, Blastoise has the potential of being a very powerful Pokemon.
Blastoise, Gyarados, and Suicune.
No, Blastoise is not a legendary pokemon.
It's cute but it's not good until it's a Blastoise
Articuno, Moltres, Zapdos, Alakazam, Blastoise, Gengar.
For the elite 4 you need: A good electric pokemon (Probably Pikachu, Riachu or Zapdos), A good psychic pokemon (Probably Kadabra or Alakazam), A good water or grass pokemon (Blastoise is good, as would be Venasaur) and a good ice pokemon (Articuno is good, as are Dewgong and Lapras). If it is your first time and blastoise was your starter, moltres or Arcanine will be useful for your rival
