For an archetype that's been out for eight entire years now, it sure feels very obscure for some reason. I only know about it from one of you guys mentioning it a while back, and even then, I've never once seen one of these cards organically. Which is sad, because I think they're interesting, especially when paired with the context that one of the inspirations for them is the German opera Der Freischütz, with this card being an excellent example of that. Magical Musket Mastermind Zakiel (background) and Magical Musketeer Max (foreground) are directly inspired by the characters Samiel and Max from the aforementioned opera. But more than that, this appears to be a rendition of one of the last scenes of the opera, where the final magic bullet is shot. Zakiel would have full control over the trajectory of this bullet (his intention indicated by his finger gun to the head), which has a tragic outcome for Max (shown by his superb expression and posture). The subtle detail of the white rose petals blowing across is what undeniably indicates when this scene takes place, even though you don't get to see what Max is shooting. Those diagonal blue speedlines in the background create a very convincing foil card illusion that it's kind of scary. This card was only ever released as a common, but I have to imagine that it would look amazing with an actual foil effect. I also must say, the glowing x and circle (and faint electricity bolts) really sell the "magic bullet" angle. Well, that and the fact that you can't see any part of Max's right arm (barely any of his right hand either), which I feel enhance the idea that he has no control over it.
I'm genuinely surprised that this card (and archetype in general) doesn't have any edits made to it for the TCG version. Changing hand positions is not unusual for them, and I feel like a "finger gun to the head" pose would be an obvious edit, but I guess not! Same goes for the pistol here, and any other guns used in these cards, really. Maybe they look just demonic enough that they didn't feel a change was necessary? Idk! Just feels a little weird to me when they'll literally edit the smallest things ever.
