The Grand Arena is back, and this time we are turning the dial all the way up. Welcome to the biggest, boldest, most ambitious Grand Arena ever.

Every Champion. Every Skill. ALL 21 CHAMPIONS are stepping into the ring at the same time for the first time. A true Massive Melee of a Grand Arena, with each Champion carrying a brand-new prebuilt deck hand-crafted by some of the sharpest minds in the MARVEL SNAP community. Pick your favorite hero, pick your favorite creator, and battle for glory.

 Event Ends

June 30, 2026 3:00 AM  The Event Shop will remain open for 48 hours after that.

What makes this Grand Arena different? 

If you’ve played the Grand Arena before, you already know the broad strokes: pick a Champion, get their Skill card in your opening hand, and fight across three locations to take down your opponent. This Massive Melee run keeps that core loop completely intact. What it changes is the scale, the source of the decks, and the names on the box.  The Champion pool is the biggest it has ever been.  

A classic Grand Arena gives you eight Champions to choose from at the start. This time, we are throwing open the doors on every single Champion the Grand Arena has ever featured. All 21 of them are available from the moment the event opens.  That includes recent additions like Magneto, Thor, Hulk, and Ghost-Spider alongside fan favorites like Carnage, Mister Fantastic, Mole Man, and H.E.R.B.I.E., plus a handful of Champions making their return in this run. 

The decks were built by the community, for the community. In a classic Grand Arena, the Second Dinner design team builds the prebuilt decks you start with. For this Massive Melee Grand Arena, we did something we’ve never done before: we handed the keys over to the players.  We invited 21 of MARVEL SNAP’s most respected deck builders, theory crafters, and content creators and asked each of them to design the prebuilt deck they believe best showcases their assigned Champion.

The Grand Arena has always been about handing players an exciting starting hand and watching what they do with it, and this run extends that philosophy outward.  Whether you’re here to run your favorite Champion, support your favorite creator, or just see what the community’s sharpest minds put together when given the keys, there is a Grand Arena run waiting for you.  Same Grand Arena rules, dialed up. 

 The 6-turn format, the 2-energy starting hand, the Skill card in your opening grip: none of that changes. Tickets work the way they always have. The Event Pass still runs 26 milestones across a Free and Premium track. But because the Champion pool is more than twice as deep this time, every match is a fresh question: which Champion did your opponent pick today, and which creator’s deck are they running? Mirror matches are rarer. Tech choices matter more. The meta has 21 ways to look at it, not 8.
