When exactly are you going to pitch dark? At the beginning of the game? Ok, well then you can't lost zone anything until you break the trainer lock, unleashing gdos's set up. What I am talking about is starting a power lock a little later, after set up. Then, your lostzoning ability will be crippled. Is that when you're going to pitch dark? Then I'll just knock out the ghastly every turn making it awfully hard for you to build gengars.
As for devoluter, it would obviously hurt gdos. Just not as much as people think. Cursed drop then a surpise flash bite+devoluter would really hurt a gdos. But that requires you to build a lostgar with devoluter and crobats! You're sacrificing more important matchups for a deck that was never the bdif or your worse matchup, and that will be played less than ever.
LoTad, apparently you didn’t get the memo saying that sideboards could be used for States (only for LostGar though). That’s where everyone is fitting their…
