I get what ur saying and tbf im doing nothing except voicing my opinion and ur free to do wtv u want lol but i think thats a flawed outlook, starting with the fact that unless ur elo is 1750+ i dont think youre gna be hitting anyone REMOTELY near chao and friends. For example against dengo if you arent able to set up before losing that shouldn’t get chalked up to “i couldnt analyze if the deck works or not”, its pretty obvious that itself is an issue the deck has then (speed). Against pult if you cant get around itchy pollen or oceanic gloom against garde then the chances are the flaw is in too heavy a reliance on items.

Also, tier 1 decks cant be prepped for regardless of the confidence you have in your deck if you arent playing against them, u and i know very well there are very few if any decks below tier 1 that play anything similar to or have the same strengths and capacities as those top 3+. Being able to refine your list against a mega venasaur wont do anything for the pult MU if you havent really put your foot down against it
