I think it's the status quo Ash. Most people are just comfortable with having a static meta where all the best decks are known.Game-breaking??? If you're in reference to this Zapdos, this is far from game breaking. It's a really good card and great support for lightning, but I would not call it busted in the slightest.
Honestly, I feel like people use that term way too much for cards that don't even fit what defines game-breaking... Since when was new good cards that can contribute to creating new deck archetypes a bad thing???
Jesus y’all don’t have an ounce of sarcasm in you
