I feel this completely, been waiting for what feels like years to actually want to spend money on this game other than random old frame singles I like. Similarly excited for Bloomburrow I think mostly because it feels like Wizards getting back to an actual fantasy motif again with some novel lore.
To expand a bit on your point on product fatigue, I’ve noticed “moving on” from new releases much much quicker these days. MKM hasn’t even been out that long and it’s already spoilers and news on OTJ and the other releases coming soon. I’ve mentally checked out of MKM already whereas before we’d have 3 months to just think about it and get to know it.
Separately, even the products designed for “me” like Ravnica Remastered with all the old frame cards are just priced too high, with no way to get some of that back by buylisting anymore it seems. $150 is so outside my impulse buy range that I invariably just pick up singles again. It could be different if I had a local playgroup again big enough to draft with but without that I just don’t feel any desire to buy sealed products or crack packs like I used to.
