cyndaquil wasnt really that good imo.
i mean.. with totodile you could teach it ice punch and beat the crap out of grass and dragon pokemon, and it learnt bite (and crunch as well? maybe? cant remember) which was awesome against the ghost dude, but cyndaquil is like.. plain fire.
though typhlosion looked extremely awesome..
also it'd be interesting to play hgss with the new physical/special split, feraligatr's ice punch will now depend on it's physical attack strength (which is pretty good), not it's special.
and typhlosions' flame wheel will depend on it's physical attack stat, not its special, and iirc typho has a higher special att than physical att.
