Although Blaziken is the worst starter of the three, you could use him on your team much more than the other two. You have a water/grass type, a ground type (dragon too, unimportant) a Salamence (this thing makes it's own type lol) and a Psychic, with an Electric attack. Try not to keep two dragons that are 4x weak to ice on your team. If you lose Flygon, the worse dragon of the two, get Swampert. If not, get the classic Blaziken with:
lol at the fact that you asked us for the best starter in your team, almost everyone said Blaziken, but you still went with Sceptile. Sceptile is kind of useless on your team, as Ludicolo does mostly the same thing. You need a fire type. If you won't take advices, why ask?
Get Rid of flygon or Salamence 2 dragons issnt needed
Blaziken in this team.
NO sceptile because Ludicolo
Swampert is option to due the fact you should use or Flygon or Salamence
That will probaly have EQ.
Ludicolo would probaly have Surf.
