Good read! I diverge from you on a couple of things.

I don't mind if the BP yields profit for the buyer, but it has to be in optional stuff that doesn't impact sales of the core product like what happened this time. With this I mean give people the opportunity to sell the cosmetics for example. Maybe there is a crafting recipe that creates a fancier cosmetic by burning 5 from the BP? This would create scarcity and exclusivity, giving value to BP buyers.

Value could also come in the form of collection rewards that boost some of the perks, such as extra Sealed tickets, more Star Points, more Flux, better Core packs, etc. But definitely do not do wacked math with Pack value like this again. Offering a board at the end, with quality tiers based on collection size could also create a lot of value for the buyer, especially if they could also be forged to higher quality tiers.

Another avenue is to distribute Meteorite art variants that can be shined up in the forge. Most people wouldn't mind parting with those to recoup the BP cost, while a few people would surely appreciate the bragging opportunity in game while still benefiting from DPE rewards.

I don't think the Mission requirements should affect the player's ability to win matches. Anything like 'no relics and no spells' cannot create competitive decks and we should stay clear of those. I do think the engine should be upgraded to keep track of a lot more stuff, bc that would enable achievements and reward tracks for all sorts of lifetime milestones, which I think it's pretty cool and helps with a progression system that keeps players engaged.

Here's some !PIZZA for your feedback ;)
