>>27243070If you're talking about the foiling, Reverse Foils from EX Hidden Legends until EX Power Keepers were fucking awesome, they were basically foils with the set logo on them and a unique foil pattern.
If you're talking about the individual card, well it's basically a better version of Team Rocket's original Dark Hypno. EX Team Rocket Returns had quite a few cards that were basically remakes of cards from the original Team Rocket set and from Neo Destiny (which also had Dark Pokemon). My favorite would probably be this one, have a complete reverse foil playset.
