Made some major changes, so I'm posting the new decklist.
Pokemon (21):
1 Magmar ex
4 Torchic (2 Singe, 2 Fireworks)
4 Combusken (2 Natural Cure, 2 Double Kick)
4 Blaziken (2 Flamethrower, 2 Firestarter)
2 Electabuzz (Base)
3 Skitty (Plus Energy)
3 Delcatty (1 Rare, 2 Uncommon)
Trainers (23):
4 Professor Elm
2 Juggler
2 Professor Elm's Training Method
3 Lady Outing
2 Potion
2 Pokemon Nurse
2 Town Volunteers
2 Switch
2 Energy Switch
2 Fisherman
Energy (16):
12 Fire Energy
4 Electric Energy
Strategy and notes: I switched from the 4-4 Manectric line to a 4-3 Delcatty line (which would have been 4-4 if it had been possible), filling in the space vacated by the 4th Manectric with a tech Scyther ex. I changed the Electric Energy to Grass to power it, dropping one for a Fire because of its lower Energy needs. I'm using Electabuzz to cover my Water Weakness. The Delcatty may not cover my Weakness like Manectric was intended to, but they combo better with Blaziken, and should still fare fairly well against a Water deck. The Rare Delcatty was added not as much for the usual reasons as for combo potential and to bring the line to 4-3, although its power should work out well with Blaziken, as it is a mini-Juggler. Its attack, however, does fit quite well in the scheme of the deck, for the same reasons as its Uncommon counterpart. The Skitty even get in on the act, giving me an extra free Energy attachment.
Main strategy is to use Blaziken's Firestarter (and, to a lesser extent, Uncommon Delcatty's Energy Call) to power up itself, the other Blaziken, or either Delcatty, discarding Energy with attacks, Trainers, or Powers to use Firestarter. My only major concern now is the high number of Supporters (13). The three singles are not much of a concern for me, although I do wish I had a second Rare Delcatty to add. The last version of this deck was actually fairly reliable, and it didn't even have the synergy that I think this one will. I can stall with Magmar ex while setting up, if needed, or I can use it mid to late game for stall or attack. I would appreciate any comments or fixes, although I would ask that no Sandstorm cards be suggested, as I do not have any. The Delcatty's will mainly be late game attackers, since they need higher amounts of Energy to deliver big hits.
