Mastery of BOTH Genetic Apex AND Shining Revelry's HITMONLEE for the WIN
DISCLAMER: As of me writing this, the deck below has gotten me into Ultra Ball 1. I have no data of how this deck does against the top 5 meta decks.
This is the best deck I've used as someone who just caved into buying the premium pass. That being said this deck doesn't rely on many newer cards or cards that are particularly hard to get.
First, leading off with EITHER Hitmonlee (while going first OR second) guarentees value within the first few turns. You will have an assortment of tools and supporters with deck disruption in order to stall for the Rare Candy. Durring this time you may even be in the possition to set up quick kills on basics running back to the bench. This is especially possible with X Speed. Drawing into X Speed within the first few turns enables some SNEAKY playes that could even lead to an early checkmate!
If you draw only one or two Ralts first, don't panic. You more than likely also drew Kirlia, Gallade, Poke Ball, ect. Gallade and Hitmonlee plus Cyrus REALLY punishess poor energy placement. Once Gallade is activated, its 170 hp gives enough time to build your second Gallade.
Minor Edit: Switched Poison Barb for Giant Cape so Gallade can survive a Red boosted Chaotic Impact from Giratina ex
I will update this post further if this deck works after Eevee Grove.
