Empoleon VS Fire Decks isn't autoloss... New Magmortar and Typholosion have 110 HP, which is 10 too much for an Empoleon to one shot (unless they weren't bad like my sister, and remembered to Aqua Shower as Prinplup)
...Wait a minute, this is old Blaze + Infernape + FireDeltaStuff. Oh. Whoops...
Okay, judging from the Infernape and Blaziken lines, it looks like you're trying to focus on them. First, cut the Primape and Latias and the other unrelated pokemon. As a general rule of thumb, if the pokemon is not helping your main line in some way (IE: Absol EX moving energy helps a spreader like Empoleon. Stantler helps search out for main hitters. Delcatty from Power Keepers provides energy in the discard for Blaziken's power), then it should not be in the deck!
If you've removed the non-Infernape/Blaziken stuff, then that's 8 cards removed. It's highly worth it to add in another Blaziken (PK/RS, whichever you happen to have a copy of). Additionally, since the PK Blaziken offers far more advantages then the HP Blaziken, it's recommended that you switch the HP Blaziken to the Firestarter. Doing this addition leaves you with 7 empty slots...
Okay, Energy time.
Remove 3 Fire energy and replace with 3 Double Rainbow Energy. This will allow you to use Flare Blitz almost constantly WITHOUT having to switch all of the time, and make it all around easier to play.
Trainers...
The following trainers have effects that are more efficiently carried out by other trainers, and thus should be replaced: Professor Elm’s Training Method, Mr. Stone’s Project, Professor Cosmo’s Discovery, Master Ball, Bill's Maintenance, Island Hermit
Replace the Professor Elm's with more Celio's Network from Crystal Guardians (to be able to search for basic pokemon as well, not just Evolutions)
Bill's Maintenance, Island Hermit and Professor Cosmo's may be able to draw cards, but they do not help set up your deck beyond this pure draw power. TV Reporter on the other hand, will leave energies in the discard for you to return with either Infernape LV.X, or Blaziken PK. Thus, TV Reporter should replace these cards.
It's often easier to get a Stage 2 out, by just playing a Rare Candy to skip the stage 1, thus you should switch your Master Balls for two more Rare Candies (from either HP or Pop5)
Now, for what to do with the 7 still empty slots...
Well, here you've got some options. The way that might prove most beneficial is to play 3 Skitty (from any set), 3 Delcatty (from Power Keepers) and then whatever you want for the last card. This gives you an increased amount of energy in the discard, as well as more draw power
You also can go with just more draw power cards. Cards such as Suzanne's Research (findable in the new Secret Wonders set, or in the Electivire Starter deck from that set) will help you get either energies or basic pokemon quickly. If you want the ability to withstand more damage, then addition of a few Castaway from Crystal Guardians and Buffer Piece from Dragon Frontiers will reduce damage and make Empoleon a less scary opponent. You've also got the option of maxing out how many of each pokemon you run (up to 4 of each card, however keep in mind that Infernape LV.X and Infernape count as having the same name)
Hopefully, this helps [del]Though I'm not in the mood for summarizing this all at the bottom. Fixes are just kinda randomly embedded in here. Sorry :/[/del]
