Death & Taxes lists often leverage it to protect threats like Thalia, Guardian of Thraben, and its effective against decks that want to cheat cards like Griselbrand into play, often invalidating them entirely

If you dont fancy you chances, there are also some great looking IRs here too, like a very picturesque Zamazenta and an Electrike that kind of looks like its pooping (Electrike also happens to be my favourite Pokmon I had to give him a shoutout)
GameStop, Best Buy, Walmart and Target aren't the only national retailers you can find modern Pokemon Trading Card Game products at MSRP (retail price)if you catch a restock, anyway
