Alright, so there's a lot to say here. First, I'm familiar with the author/artist duo through their doujin manga Onanie Master Kurosawa, which I consider to be one of my favorite manga. I happened to re-read it... uh, sometime in the past five years, by which time they'd started work on DESTROY ALL HUMANS. THEY CAN'T BE REGENERATED, which interested me pretty much only because I like OMK. I was largely unfamiliar with Magic the Gathering by this time.
So, that's kind of incorrect; I've been aware of MtG for almost as long as I've been aware of Yu-Gi-Oh!, as the cards were always located near each other in stores. I essentially grew up with YGO, among other "toy/game advertisement" anime localized in America in that era (the late '90s to mid '00s). MtG never appealed to me. The big thing, which I was telling a friend at work a year or so ago (he's into Magic), is that there was no, like, "Saturday morning cartoon" to advertise the game, and I was an easy-going enough kid that I could have easily had the game shilled to me with a cool show, like aforementioned YGO, or like Beyblade also. In fact, I am aware of another Magic manga: Duel Masters, which I understand began life in Japan as a manga about MtG, but which Wizards of the Coast eventually developed into a somewhat unique game (with similar elements like the five colors and "tapping" cards, &c.), and which came stateside with the dub of the promotional anime (which, incidentally, was given a gag-dub so as not to step on YGO's toes too much...). I did not at the time realize Duel Masters was basically anime-Magic, and, if I did, I might have been more interested in "graduating" to Magic after Duel Masters kind of... just fucking died in the West.
I mentioned a work buddy above, and he's kind of significant for my kinda-sorta knowledge of Magic today. He mentioned early in our time at the job that he was into card games, so I asked him what kind(s) because I kind of wanted someone to help nudge me back into YGO (I dropped out when Synchros came up and got back into the anime over a decade later with VRAINS). My friend was instead only into Magic, and the Commander format specifically. He helped me to learn the game, and we would play mock-duels by posting screenshots of our boards on Teams during work, when possible. But we weren't using physical cards, and he was testing fantasy decks he might not be able to afford, while I was testing digital versions of preconstructed Commander decks that might be easier for me to purchase. My cards, naturally, kind of sucked. And my main lesson was that the real game is "pay to win." No one buys booster packs to build decks; that's what the singles market is for, but the best cards will cost an arm and a leg.
Due to... poverty, I guess... I started losing interest in Magic, before ever actually physically playing the game (besides, like, Solitaire-esque duels against myself using Jumpstart packs...). I did meanwhile buy a booster box of the then-latest YGO set, but only pulled trash. I started getting more into a trio of Bandai card games (Dragon Ball Super, Digimon, and One Piece) as well as occasionally buying the stray Pokemon booster, and eventually moving on to Japanese Pokemon booster boxes (which have superior pull rates compared to the dogshit in American product). I'd always kept an idea in mind that Magic's Sealed Draft format might be extremely interesting, forcing you to use the chaff available from random boosters, but my friend exclusively played Commander and I... simply didn't want to go to my LGS as a total newbie and fuckin' lose.
I got back into (the idea of) Magic with the Final Fantasy set, despite thinking the Universe Beyond stuff is stupid in general - actually, another reason I couldn't hold interest in Magic was the apparent lack of aesthetic cohesion with its multiverse stuff; the first set I bought was WOE, followed by LCI, then MKM and OTJ, which was the last set I bought from until Foundations, then I took another hiatus until FIN. I decided to view FIN as its own thing, and I was buying product as a fan of Final Fantasy first and foremost. But I opened a Play Booster Box between yesterday and today and didn't pull anything especially rare (though I did like a lot of cards I got, as it seemed WotC honored the franchise's flavor way better than they did Tolkien...).
Final Fantasy is important to note because of the setting of this manga: it follows otaku in the late '90s, and protagonist Hajime explicitly references FFVII and FFVIII (as well as other Squaresoft RPGs like Trials of Mana, Xenogears, and Bahamut Lagoon). I'm sure the protagonist would love the FIN set, though I'm a little upset to learn the manga ended in Japan last month, before this set dropped.
So far, I cannot imagine this manga will follow the span of emotional beats I might expect of Onanie Master Kurosawa, but there are at least similar feelings of adolescent angst, naivety, innocence, and joie de vivre that weigh heavily on the Nostalgic portion of my heart, even if I don't quite feel all the direct references to Magic. In a way, the manga reinforces my desire to get more into the game. But I also feel it would be impossible to simulate what Hajime and Emi feel here. The game seems different now. I think more people play Commander than Standard. I'm 31 instead of 13. My age and occupation allow the possibility of just fucking buying singles to build decks instead of facing the randomness of cracking packs, so there will never naturally be any feeling of improving a deck or collection unless my willfully crippling myself (either by forcing myself to stick with boosters instead of singles, or just assfucking my finances by buying better single cards). I also just kind of have this "thing" where I feel uncomfortable having "nerd" friends who are too passionate about their "nerd" interests without balancing them with (for deliberate avoidance of a better word) "hipster" interests (e.g. avant-garde literature or cinema).
The first time I read Onanie Master Kurosawa, it made me want to love and cherish more the friends I had at the time. The second time I read the manga, it made me value my self-imposed solitude, like I'll never really be able to value connections with other people again, if I'd ever truly done so before. This manga kind of makes me feel the same way as the latter experience; it's "too late" for me to get into Magic the way Hajime is, and I wouldn't be able to trust the Sincerity of anyone emulating Emi.
EDIT: This is kind of important to include, but I forgot about it because of how long it took to write the review: I got distracted by getting back into Arena between finishing this book and reviewing it. Turns out, I am just not good at this game.
