Choice Scarf Starter

Choice Scarf Mild / Rash
Moveset EVs
~ Eruption
~ Focus Punch
~ Overheat / Will-O-Wisp
~ Earthquake / Hidden Power Ice
144 Atk / 252 SpA / 112 Spe

This set is meant to be a leading Typhlosion. Typhlosion got the move Eruption in Diamond and Pearl, and, coupled with 100 base Speed, 112 Speed EVs and Choice Scarf, it can use it first before any Pokémon having up to 130 base Speed, except other Choice Scarfers, for a lot of damage. 144 Attack EVs allows Typhlosion to 2HKO the Blissey that comes in, expecting Eruption, with Focus Punch. Overheat is the fire move of choice when your HP is low and Eruption is not powerful anymore, especially if Blaze is activated, but Will-O-Wisp is an option if you want to mess with leading physical attacking starters. Earthquake counters Flash Fire Pokémon like Heatran and Houndoom, but Hidden Power Ice may be preferable if there are too many Choice Specs Salamence starters in your neighborhood.

SubBlaze

Petaya Berry Timid / Modest
Moveset EVs
~ Substitute
~ Fire Blast / Flamethrower
~ Hidden Power Ice / Solarbeam
~ Sunny Day
4 HP / 252 SpA / 252 Spe

This set takes advantage of Blaze. Substitute down until Petaya Berry activates, using Sunny Day in the process. Then use your preferred Fire move; Fire Blast is the more powerful, but you might not like its accuracy, while Flamethrower is less powerful but accurate. Fire Blast boosted by STAB, Sunny Day, Blaze and Petaya Berry does between 69% and 81% to Blissey. Hidden Power Ice and Solarbeam counter Dragons and Swampert respectively.

Sunnybeamer

Leftovers Timid / Modest
Moveset EVs
~ Sunny Day
~ Solarbeam
~ Fire Blast / Flamethrower / Eruption
~ Hidden Power Ice / Hidden Power Electric
4 HP / 252 SpA / 252 Spe

Typhlosion, together with most other Fire-types, gets Solarbeam now, giving it a even more immediate counter against Water Pokémon. This is a rather standard Sunnybeamer, but gets STAB on the Fire move, rather than the Grass move for the traditional Grass-type Sunnybeamers.

Choice Specs

Choice Specs Timid / Modest
Moveset EVs
~ Overheat
~ Focus Blast
~ Fire Blast / Flamethrower
~ Hidden Power Ice / Hidden Power Grass / Hidden Power Electric
4 HP / 252 SpA / 252 Spe

A Choice Specs set is in order after recognizing Typhlosion's good Special Attack and Speed stats. Sadly, Typhlosion doesn’t get too many options in this regard. A well-predicted Focus Punch does the same amount of damage to Blissey as Focus Blast would, even with a nature hindering Attack, so it can possibly fill in the Fighting attack.

Other Options

It gets a nice array of physical moves, like Flare Blitz, ThunderPunch and Shadow Claw, and Howl to boost them, but Typhlosion should not go completely physical. Note that Flare Blitz and Howl are both egg moves, but nevertheless, Typhlosion can have them both in the same moveset by breeding them from Growlithe. Lava Plume has a 30% chance of inflicting a Burn on Gyarados, Salamence, and Garchomp trying to switch in, but Typhlosion is a bit fragile and prefers power over added effects.

EVs

For the Choice Scarf set, you might prefer to sacrifice some EVs for even more speed to outspeed Choice Scarf Heracross, but otherwise, go with the listed EVs. For every other set, just go with maximum Speed and Special Attack.

Opinion

Typhlosion got boosted by Eruption and, to a lesser extent, Lava Plume and Solarbeam in DP, but, unfortunately, the advent of Stealth Rock makes it very difficult to use without a lot of Wish support. Because of this, most players will probably shy away from this Pokémon, preferring to use something that requires much less support. Still, Choice Scarf Eruption can provide a very good payoff if well predicted, so all is not lost for the fire GSC starter.

Counters

Stealth Rock will wear down all Typhlosion sets eventually, but there are also specific counters for each set.

Flash Fire Pokémon counter the Choice Scarf set as long as they watch out for Earthquake.

Against all other sets, Blissey is the sure-fire counter of choice, especially if she is at 100% health. If it isn’t, watch out for the potential 75% damage that can be done to it by the second set. Milotic is also very good since it gets boosted by a Lava Plume burn. Without Hidden Power Electric, Gyarados is a good enough counter as well. Thick Fat Snorlax is also a counter if Typhlosion does not use Focus Blast.
