When Magic: The Gathering shadow-dropped its Marvel Secret Lair on April Fool's Day in 2025, the internet collectively squinted. Deadpool riding a unicorn towards Jeff the Land Shark, who was also riding a unicorn? Clearly a joke, right? Wrong. The set was real, the cards were glorious, and tucked inside the promotional box was a hidden bonus card that has since become the stuff of collector legend. By 2026, it's safe to say that nobody is laughing at that so-called prank anymore—unless it's out of sheer, uncontainable delight at the gummy-shark-faced chaos that has overtaken the multiverse.

Let's rewind the clock a bit. Before Marvel Rivals transformed Jeff the Land Shark from a deep-cut comic darling into an omnipresent adorable predator, the little guy was mostly known to Gwenpool readers. Then Rivals happened. Suddenly, Jeff was everywhere—plushies, memes, tier lists, and apparently, Magic: The Gathering. His Secret Lair debut was a reskin of the card Harmless Offering. Instead of presenting a cat, the artwork sees a beaming Jeff being handed over by none other than Gwenpool herself. Mechanically, you’re forcing an opponent to take control of a permanent you control, which means you can literally gift them a tiny shark with zero chill. Why would you do that? Because you can, and because Harmless Offering has never been this unhinged.

Now, a question that haunted collector forums throughout 2025 and into 2026: Why wasn't Deadpool holding Jeff in the bonus card? The front-facing cards already had Deadpool gallivanting with unicorns and katanas, so slotting Gwenpool into the hidden slot was a stroke of genius. It not only kept the bonus card distinct, it also honored a comic-book truth—Gwenpool and Jeff are basically inseparable in the source material. Marvel Rivals might still be holding out on that team-up (are you listening, NetEase?), but MTG snuck them into canon together before anyone could blink.
What makes the bonus card so captivating, even a year later, is the sheer audacity of the drop. Secret Lair releases are typically teased weeks in advance, with calculated hype cycles and exclusive windows. This one? Announced on a Tuesday, sold out by the time you'd finished your coffee. No leaks, no previews, just the universal shrug of April 1st. It followed on the heels of the SpongeBob SquarePants Secret Lair, which had been a full-blown event with multiple bonus cards and a cardboard Bikini Bottom. Deadpool's set was the antithesis—a chaotic good ambush. And when those who snatched it up started cracking it open, the discovery of Gwenpool cradling Jeff spawned a thousand reaction videos, each more unhinged than the last.
Of course, the real treasure here is the slow-burn realization that Jeff is now a permanent fixture in MTG's expanding Marvel corner. By 2026, we've already seen the Spider-Man set hit shelves with its own multiversal shenanigans, but Deadpool's Secret Lair was the canary in the coal mine. It proved that Wizards of the Coast could drop anything, at any time, with zero warning. Could there be a Gwenpool legendary creature lurking in an unannounced supplemental product? Will Jeff get a full commander deck built around handing permanents to opponents? The possibilities are as endless as Deadpool's fourth-wall breaks.
Collectors who managed to snag the Secret Lair now guard their bonus cards like dragons hoarding treasure. For everyone else, the secondary market has been, shall we say, unkind. It's a stark reminder that in Magic's universe, the most ridiculous characters often end up with the most beloved cards. After all, who could have predicted that a legless land shark would become a more sought-after Magic card than half the legendary creatures from the last five years? Nobody, and that's exactly why Secret Lair exists.
Looking ahead, the Deadpool drop set a precedent. If MTG can canonize Jeff on a random holiday, what's stopping them from dropping a Howard the Duck saga? Or a Squirrel Girl food deck? The Marvel and MTG crossover is no longer just a planned expansion; it's an ongoing narrative that can ambush players at any moment. And for that, we have Deadpool, Gwenpool, and a small, perpetually smiling shark to thank. So next time you sit down at a Commander table and someone drops a Harmless Offering variant featuring Jeff, just remember: you're not just losing the game—you're participating in history. 🦈✨
