Typhlosion>Emboar, because of the reasons mentioned so far, and the fact that if Typhlosion gets dragged active for whatever reason, it can either attack with Flare Destroy for 3 in a pinch(by afterburnering to itself, thus speeding up the energy attachment process) or retreat for the somewhat manageable 2. If Emboar gets dragged active, you have to either drop 4 the old-fashioned way to do an AMAZING 80, or burn 4 to RUN AWAY. Both are pretty bad.
Typhlosion just does the tech job much better than Emboar. Besides, if you run the Emboar/Fisherman combo, then you essentially edit Ninetales out. This is not a good thing due to the very minimal draw power in the format now that Claydol isn't around. Ninetales is one of the top 2 draw power engines, next to Magnezone Prime, and a fire deck not running it is really not an option. It's just too good.
There isn't a darn thing wrong with Fisherman using up your supporter for the turn if you really need it, but if you can find a way around it, and in so doing use your supporter on something else, than that's the better option
Oh, and so I don't get warned for the umpteenth time, I believe the rotation will be RR-on. A mid-season rotation seems completely illogical to me. RR-AR have not had enough time in the format and a random cut of 6 sets IMO is just not gonna happen.
