I mean, from what I understand you can't teach Typhlosion Solar Beam or Focus Blast yet, and in my opinion Extrasensory is situational at best. Too bad that Typhlosion can't learn Grass Knot, but if you get lucky you can get Hidden Power Ice, Water or Grass (or breed for the HP you want, if Reborn uses that mechanic - I have never bred any Pokemon so I don't know).
Despite these shortcomings, Tyhplosion does well throughout the game even with mostly Fire-type moves. Either I overestimate or you underestimate how good fast Fire-types are in this game. The Gym Leaders who use Fire-resistant types such as Rock, Dragon and Water haven't appeared yet, and the field effects that weaken Fire are few and far between. Quilava/Typhlosion definitely contributes in most, if not all, Gym Leader, Rival and Team Admin battles thus far.
