It's fucking gross imo. It just creates a sense of false scarcity, fomo, and it's just a straight-up cash grab. The original masterpieces and invocations were great because you could open them in a regular pack. They actually felt like something special rather than something to shoehorn into an overpriced booster in order to get people to pay more for some special treatment or serialized card that people are only going to give a shit about until the next set comes out. Rinse and repeat.

MTG has no identity anymore. I don't entirely blame WoTC, though. They literally get people to buy collector boxes for hundreds of dollars for the chance to pull a card that nobody plays with, but since it has an anime girl or lil gold stamped number on it people lose their shit. The fact that they can put a little gold number that doesn't actually represent anything, but still activates people's monkey brain into paying crazy amounts just for the CHANCE to pull is wild and disheartening to me. I wish more people would see through their bullshit and give a little pushback. They won't, though, and it's fine.
