Teysa works better with some cards than others and being a touch on the luxury / win-more side of things you do have to be a little careful with her
Here are a few pricier cards that Id suggest trying out in the deck
Attack 2 : Fire Charge Hit If your opponents pokemon is a Stage 1 this attack does 1,000,000,000,000,000,000,000,000,000,000 more damage
With a 10-year limited warranty included, I think this is a dependable storage upgrade for devices like cameras, tablets, or handheld consoles (...but not Switch 2)
10 Pharika, God Of Affliction Pharika may not technically have the Snake creature type, but shes an honorary Snake in everything from appearance to abilities
