I find deep satisfaction in deck building when it comes to trading card games. The challenge of putting together a competitive deck is a wonderful feeling, especially if there’s a good way to get rapid feedback with play testing. If a TCG has a well balanced and diverse meta it’ll have me as a dedicated player. This was one of the reasons I eventually gave up on Hearthstone, because each expansion found a way to imbalance the game in a new and unique way, and completely break the previous meta game. Pokemon seems to succeed here. Expansions build on each other, and don’t completely reset the meta, but instead allow it to evolve.
