with the rise in Electric decks, and the upcoming Darkness creep, AND Mewtwo's making heavy energy attackers suffer, I think it's time to look at Donphan again. if even it's likely going to be rotated out.
pros = easy search thanks to heavy ball and the Phanpy can be searched out with Level ball or dual ball. low energy, high HP, uncommon weakness, common resistance. can abuse max potion.
cons = Tornadous, heavy retreat, basics have low HP in this format.
the list:
4-4 Donphan Prime. (I use the CoL Phanpy because it has a pokebody that lets it not take EQ damage)
Pokemon: 8
3 random receiver
1 Dual Ball
3 Level Ball
4 Heavy Ball
2 Lost Remover
2 Catcher
4 Junk Arm
4 PONT
2 N
2 Bianca
2 Crushing Hammer
1 Max Potion
3 Switch
1 Super Rod
1 Energy Retrieval
1 Ruins of Alph (for Tornadus)
3 Plus Power
1 seeker
TSS: 40
11 Fighting
1 Rescue
Energy: 12
there is enough fighting that you can setup a few heavy Impacts if need be. heavy PP to one shot Zekroms with EX. 2 Lost Remover since once you play a second, they'll know you can junk arm for more, or you might run a heavy lost remover count. making them only attach basic energy, making Crushing hammer even better. since Eaerthquake only takes one energy, they can't successfully Catcher a non energy donphan, since you can just attach an energy and attack. Switch is just in case they SP conditions you while not trainer locked.
the heavy Trainer Count makes Mianca almost as good (in some cases Better) than Juniper.
