If this was the Worst Move You Ever Made thread, I can assure you someone would have posted "Well, it was in the Regional Championships, me playing Sableock and my opponent was playing Charizard. I go first and Impersonate for a Black Belt."
Anyway, at league at 9pm, I was playing against this Master that's my friend. So I am first, and I had WORST HAND EVA. I used Copycat second turn and still nothing significant. I PONT and get T-Tar Prime + Rare Candy and I already have a Larvitar on Bench. So evolve, Warp Point, I bring up T-Tar with Special Darkness Energy and Expert Belt. He only has one thing on his Bench. Sunkern. Darkness Howl KO. His other thing was useless and he had a jacked up hand. His deck is kinda bad though (it's a grass type deck, no Landmin, Skymin, or Leafeon). So yeah, it was an okay game. I was just lucky to get the Energy, because I don't run many and getting it was total luck.
