The only card that I care about this rotation was Unown Q. The card felt perfectly balanced and, now, without it, I'm missing something. It remedies getting the wrong starter and is overall good. The donk factor was worth it. There are a lot of other good cards that will be missed, but Unown Q feels like the one that I'll truly dread not having. We will adjust to the new metagame without Uxie, Sableye, Spiritomb, Ebelt, etc... but Unown Q... man... that is a big loss. Without Unown Q, Smeargle is a lot less playable. Collectoring for a free retreat felt very good... Unown Q also allowed pokemon with 1 retreat cost to be very competitive. Can't believe THAT is the card that I miss the most... but it feels like there's a hole in my decks without it :'(
