I have been playing swampert/latias/ton for some time now. We discussed it here on this board. Contrary to what some think, it's a good deck. It has tested well and performed good for me @ tournies. I played it saturday at the shack. Here's the list I am playing:
The 100 damage machine
19 pokes
3 latias ex
3 mudkip water gun or fury swipe
2 marshtomp slash
3 swampert water call
2 skitty
2 delcatty
2 magnemite random spark
2 magneton
23 trainers
4 oaks research
4 oracle
3 professor elms training method
2 lanettes net search
2 rare candy
3 nav
2 master ball
2 switch
1 tv
nrg 18
8 water
6 fire
4 electric
I went 4-2 in swiss and ending up winning the single elimination. I beat salamance,gardylord, and aggron in the top 8. The deck lost to muk ex (no chance) and machamp (drag off killed me). My strategy was this. Build 2 swamperrts and 1 ton and delcatty with a latias active. Discard 2 for 100, trade 1 card for 2 nrg, use swamperts power and repeat. There are tricks to the deck. For instance, I found that 2 fire on the active latias is best. That way you can double attach with swampert on the active and attach a fire to the bench. Wobby causes it a few problem. I pplay switch. I like to have one nrg on a benched poke, sometimes swampert, ton, or delcatty. I use the power of double attaching for a quick power up. Be careful if you use ton to attack. If ton goes down and you TV'd already, it's over. Your better off fighting wobby with swampert (auto sleep is wonderful) or delcatty. Losing catty does not hurt the deck much. I prefer lanettes over sparce. I want to attach to latias 1st turn and be doing 100 ASAP. Sparce does hurt latias.
