This is currently my favorite deck in standard format. I think it is the perfect counter to most of the meta including Lost Box decks, Lugia VSTAR, Mew VMAX, and Regis. It goes without saying the Galarian Weezing’s Neutralizing Gas ability is the key to this deck, shutting off all of your opponents’ abilities while keeping yours intact. Bibarel provides much needed draw support. Crobat VMAX provides an adequate attack with its Max Cutter, but also its Stealth Poison, which allows you to switch back into your Galarian Weezing to keep the ability lock going. Radiant Hisuian Sneasler ramps up the poison by making 6 damage counters in between turns.
Yell Horn adds even more pain by confusing your opponent while they are poisoned. Galarian Mine locks them in play, meanwhile Hiding Energy allows you to switch out your confused Pokemon for free. A major part of this deck is disruption. Not only are you severely limiting your opponents option with ability lock and expensive retreat, but cards like Marnie and Judge ensure that your opponent will have limited resources in their hand to dig them out of this hole. Just remember, it is crucial to get your Galarian Weezing in play ASAP, ideally on your first turn that you can attack.
