Ah I think I used the term "I'd argue" in the wrong context here, guess it's more correct to say "I feel". Either way I agree, and I do keep my decklists on my phone specifically for this reason when I play at my local shop. Funny enough I find these games are the most enjoyable since people are great at matching power level when you show them what you're doing.

Most of the games I get in are with my long-time friend group though and they're pretty resistant to discussing power level. We deal with frequent power level mismatch because of this but nobody wants to have the pre-game discussion so it feels like if I want to play games that are relatively evenly powered it falls to me to get my decks to a point where they're roughly the average power level.
