Countering Magnets would just be an added bonus. The main point I was trying to make is that those decks run more cards, therefore they have more resources and answers in a duel. I was trying to guage whether people think this gives them a big advantage over decks that run only 20.
From your comment, I can infer that you believe that the consistency 20 card decks bring is better than running more.
However, my question to you is, if the meta currently has many decks that run 20+ cards to much success, does the consistency drop that much? There's been many occasions I've bricked with a well balanced 20 card deck and I'm sure I am not the only person to do so.
