Fire-type

I find Arcanines work well as they are a bit more tanky thank Flareons (glass cannons). Have to find what works for you for dodging etc.

Also though they are changing STAB and Effective type bonuses. You might want to look at getting a good attacking Pinsir with double bug moveset. It will be more effective than fire. Again though you will need to be good at dodging but the bonus to double effectiveness is going to be big.

What are the CP of those fire types?

I vote Arcanine because he can best double as a defender. The Typhlosion is more than capable of doing any task you might need a fire pokemon for. The only no is Flareon, as fire blast is strictly inferior to his other charge moves.

If you want to take down Eggy, you're going at it wrong. The most effective Exeggutor counter are bugs - Eggy is doubly weak to bugs. Scyther, Pinsir, and Scizor with bug moves shred eggy. Scizor is particularly deadly, since he resists both grass and psychic, as well as eggy being double weak to bug.
Fire still works, but just as well as flying, and a bit better than ice, dark, ghost, or poison. Many of the last group are weak to psychic.

That is insane! even with the event you don't have a charizard? I personally think those are all good, have gotten 3 Typhlosions and ofcourse 2 were solar beam. I agree with the Typhlosion statement too, Just wish i had a better one.

I'd go for Flareon and/or Arcanine. They're stronger than Typhlosion; both your specific pokemon as the entire species.
Your Typhlosion might do more dps than Arcanine with the charge move, but Arcanine does (quite some) more dps with the quick move.
Arcanine is a lot tankier too.

But honestly, your Typhlosion will probably do the job well too, so if you prefer it just go ahead and level him.
It's the worst choice out of those 3 you already have though.

Hi guys! I was wondering what do you think about Houndoom as an Exeggutor counter?
