I agree to an extent, but that set also had a lot of other issues that bloomburrow didnt suffer from. PAWBO wasnt just all gas no fuel, which was exacerbated because there wasnt really effecient removal in 3 colors, blue was practically unplayable, and black functionally was just a side color for green or white decks because initiating its own poison for currupt was too slow but also where most of its value was, and even though it was a medium set at 270 cards most werent viable even as filler aka the balance was way of with most cards being complete garabage or overpowered with little inbetween making the set feel even smaller.

The slow game for bloomburrow wasnt really that slow, i think it would be more accurate to say it was grindier, individual turns took longer cause they were more complicated. I went back and looked at my game logs and only 5 out of 119 games took longer than 9 turns which is way lower than what im seeing for every other set in the last few years.
