In many regards, I was fairly conflicted about what to ban in in this metagame. At first thought, I felt the Night March Pokemon themselves should be the target to ban, as that was a ridiculous strategy in its own right, ever since the trump card ban. At the same time, the battle compressor was also utterly overpowered in its own right, and made playing the game feel... well... "Artificial" is my word for it.
With cards nowadays, discarding cards turns the discard pile into a ridiculous giant locomotive to fill up and throw at opponents. I thought the original mission of a pile like this was to hold cards that one can't use again, unless there is a price to pay to get the cards. But now, the ways we have of effortlessly 'fishing' cards from the discard into your hand, and strategies that are heavily reliant on Pokemon discarded, it's now obvious: Discarding is a huge premium for many decks now.
With this in mind, I'm wondering about the health and the role of the discard pile itself in the game. How far must the discard pile be manipulated by other cards before the mechanic creates broken strategies? My head hurts trying to think of how to solve this... Maybe as much as the compressor is overpowered, so are the cards like VS Seeker, Maxie/Archie, and Puzzle of time as well. :/
