How does Typhlosion compare to others vying for a slot on a Sun Team? Namely, Solar Power Charizard (even though they play different, they both aim to deal severe sweeping damage) and of course, Heatran.
Typhlosion seems mainly to compete if you want a reasonably fast scarfer capable of dealing ridiculous damage, or a Specs nuke capable of destroying all in its path (that doesnt have Flash Fire).
Charizard is probably the only other who has niches primarily in these roles, except maybe Heatran or Shandy.
Zard has arguably better coverage than all the others, as well as significantly more pwer due to SP. However, to say it is suicidal is an understatment, as it is horribly SR weak and its health drains rapidly.
Heatran has the best typing and a very useful Fire immunity, as well as not being SR weak. However it is arguably better in a supporting role due to its bulk, less than spectacular speed and usefulness as a defensive pivot.
Shandy has excellent power and reasonable coverage, as well as FF to absorb Fire attacks. It's typing is a mixed blessing - it can take Fighting hits if your team needs it, but can also be very easily pursuited to death by TTar, who you really don't want to make your team weak to. Arguably better with a Sub set for this reason, as well as due to its low speed.
Typh has awesome power too due to Eruption, but very lackluster coverage. FF will be useful when it is released, but currently blaze allows you to switch to FB rather than Eruption once you take some damage.
In terms of a Scarfer I'd try Typh due to his speed and not being suicidal, but if you can deal with SR try Zard.
Specs I'm not too sure, I'd probably go with the same again.
