I made it to Ultra Ball 2 in ranked this last go around with a Tapu, 1 Gengar EX, and the OG "Bother" Gengar instead. I know the sleep is powerful, but the increased dependence on Supporters in the Meta made this surprisingly good especially if it could get online quickly (which happened fairly often). A haunter and Celestic Town Elder gave the option of 2 uses of Tapu or 3 Gengars in longer games, depending on the need, which often was enough to catch DarkTina decks offguard when they get rid of it then think they can finally stack energies. Ultimately, the difference I think in energy cost between 1 and 2 is much bigger than people think, so I'd still consider the OG Gengar a threat, even if it isn't S-tier.
