Typhlosion Moves

I think...Lapras maybe? If they still exist. You do stab fire moves and super effective grass moves while resisting all lapras ice attacks

In terms of type advantages, your best match up with that would probably be Piloswine (because both fire and grass would be super effective) - especially a Piloswine with double ice moves (which you'd resist).

...that is, if you ever saw one in a gym. Save it for Manoswine maybe?

There are stronger fire types for attacking gyms, particularly the relatively common FS/OH Flareon. There are also better fire type prestigers, in the rare instances where you'd want one, such as FS/OH Ninetails. In short, I wouldn't expect Typlosion to be a good choice for gym battles, regardless of moveset.

Sounds like a great definitive set. If only Typhlosion was a defensive Mon....
