Please help me! I built Donphan / Flygon (I chose Flygon over Trevenant because the store where I bought all the stuff didn't have Trevenant, and I mean if anyone would do well with Donphan / Flygon it would be me.) for a friend who I'm trying to get into the game, and I fell in love with the deck. It won against several decks including Virizion / Genesect. The only games it lost were the ones where it couldn't set up due to a combination of dead hands and early pressure. Even if your opponent is playing smart with a low Bench, Flygon's Ability activates twice by the time it comes back around to your turn, so you have a minimum of 60 extra damage thanks to Flygon. So that's 40 (Spinning Turn) + 20 (Strong Energy) + 20 (Fighting Stadium) + 30 (Silver Bangle) + 60 (Sand Slammer) = 170. That's significant. The only problem is of course the set up, but like that's ever stopped me before. If I can get some Tropical Beaches, I would definitely play this in extended (depending on the meta of course).
