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:
Blaziken
Fire Blast/Overheat
Sky Uppercut
Bulk Up
Rock Slide
