Help How to beat Garb box in expanded with Turbo dark

[gumball51321]

Okay, I'm playing Turbo Dark in a league cup this Saturday and I'm terrified of Garbodor. The prize trade favors them, Black Ray GX puts everything on my board within KO range, and they get to attack for a lot cheaper while Ability locking me. I guess another problem is why I don't just play Garb Box, because it's BDIF for expanded, especially since I could just get the list from the people who created the deck (Brad Curcio and his play circle). The simple answer is: I don't want to. But I could just use some advice, since I couldn't think of any possible way to win this matchup with both players having an optimal game

Here's the closest thing to a solution I came up with: never bench Hoopa and try not to bench Lele or Shaymin, and attack as often as possible with the GX, since it requires the least amount of items to do KO damage. Problem there is Mimikyu with a Band does 160. And if they don't Band Mimikyu, then doing 130 means a Black Ray next turn would take the KO.
