Team - Charizard, Gengar, Emboar, Hydreigon, Garchomp, Palkia. All within mid to late 70s level wise.
Strategy - Lure in and take out opposing Garchomp ASAP by any means necessary. Cynthia started with Spiritomb while I bought out Palkia (Grngokillr) and immediately dropped the Spiritomb with a Spacial Rend. She sent out her Garchomp next which was just what I was anticipating and immediately bought back Palkia to send out my Garchomp (Homocide) as well, my Garchomp may have been a few levels lower than Cynthia's but it was faster thank the lord and I landed a pair of Dragon Claw strikes before she nailed me with a Dragon Rush, the first one missed but the second connected nearly fainting mine, both of our Garchomps were in the red and I thought about bringing out Hydreigon (Ghidora) at first but decided to keep Homocide in and finish her Garchomp off with a final Dragon Claw, Cynthia thought she could outspeed and KO me with another Dragon Rush but that risk ended up screwing her over indefinitely as Ghidora and Grngokillr cleaned up the rest of her team with minimal effort.
