LEGO Marvel makes a major thematic rotation in 2026: sets from the Avengers: Infinity Saga (2008–2019) make way for Multiverse Saga content. Ten sets are going — from the 3,093-piece X-Mansion down to small display build figures. But urgency varies enormously across the list. Only one of them demands action right now.

Last-chance decision rule
With sets moving toward retirement, waiting only makes sense while there is still enough reliable stock. Look less at the biggest price drop and more at how many trustworthy retailers still carry the set. Once availability narrows to marketplace listings or prices climb above RRP, the calm buying window is over.
| Signal | What it means | Action |
|---|---|---|
| Several major retailers in stock | There is still price competition | Keep the price alert running |
| Only one or two reliable retailers left | Stock is becoming fragile | Wait only if the set is not a must-have |
| New stock sits above RRP | Scarcity is starting to price in | Buy deliberately or skip deliberately |
From the sets in this guide, I would track 76294 X-Men: The X-Mansion, 76325 Avengers: Age of Ultron Quinjet and 76313 MARVEL Logo & Minifigures first. Not because those are automatically the best deals, but because a price move on a larger or more giftable set changes the buying decision fastest.
The ten retiring sets
| Set | Pieces | RRP | Urgency |
|---|---|---|---|
| 76294 X-Men: The X-Mansion | 3,093 | € 329.99 | Very high |
| 76325 Avengers: Age of Ultron Quinjet | 1,131 | € 119.99 | Medium |
| 76313 MARVEL Logo & Minifigures | 931 | € 79.99 | Low |
| 76324 Spider-Man vs. Oscorp | 808 | € 129.99 | Low |

| 76323 Avengers: Endgame Final Battle | 621 | € 99.99 | Medium |
| 76329 Miles Morales’ Mask | 487 | € 69.99 | Low |
| 76297 Dancing Groot | 459 | € 44.99 | Low |
| 76327 Iron Man MK4 Bust | 436 | € 59.99 | Low |
| 76316 Fantastic Four vs. Galactus | 427 | € 59.99 | Low |
76294 X-Mansion: buy it now
The X-Mansion (3,093 pieces, RRP € 329.99) is the only set on this list I’d call a genuine panic buy. Here’s why: it’s the first large LEGO X-Men set ever built at headquarters scale. Across LEGO’s entire Marvel history, X-Men have barely been given serious large-format treatment — the focus was always on Avengers and Spider-Man. This set packs seven X-Men minifigs: Professor X, Wolverine, Cyclops, Storm, Jean Grey, Beast and Mystique. Whatever comes next with an X-Men licence will have different characters or a different scale.
On the second-hand market, I expect the X-Mansion to clear RRP quickly after retirement. Scarce sub-theme HQ sets — compare the behaviour of the 76052 Batman Classic TV Series Batcave or the 75159 Death Star after retirement — typically reach 120–160 percent of RRP within six months. The same mechanism applies here: limited supply, unique minifig lineup, no announced successor.
The Avengers Saga sets: weigh up calmly
Three Avengers sets retire together:
- 76325 Age of Ultron Quinjet (1,131 pieces): the third LEGO Quinjet in the series. A solid Avengers set, but LEGO releases Quinjet variants regularly. The Age of Ultron version isn’t distinctive enough to warrant real alarm.
- 76314 Civil War Action Battle (736 pieces): the Cap vs. Iron Man scene. Good play set, modest display value. The second-hand market won’t rate this particularly highly after retirement.
- 76323 Endgame Final Battle (621 pieces): Captain America with Mjolnir. An iconic film moment, but a small set. Second-hand expectation: gently rising, no dramatic value jump.
For those wanting to close out the Saga as a complete collection: the three together run around 250–300 euro at current RRP. Waiting for Black Friday price drops in Q4 2026 is a realistic option here — they’re far less scarce than the X-Mansion.
Spider-Man vs. Oscorp: skip it
76324 Spider-Man vs. Oscorp (808 pieces, RRP € 129.99) features Norman Osborn in his civilian form as a minifig — not as the Green Goblin. Its successor, 76342 Spider-Man vs. Mysterio: The Daily Bugle (2026), is a better set on almost every measure. If you want both villains in the minifig collection, buy the Oscorp. As a build, there’s no reason to rush.
The Oscorp is also a textbook example of the licensed Marvel second-hand pattern. After retirement, the price dips 10–20 percent in the first 6 months — there’s no immediate demand spike the way there is with large non-licensed sets. Recovery only begins once actual stock dries up. If you’re patient enough to wait 6 months after retirement, you’ll probably pay less than today.
How licensed Marvel sets behave second-hand
This is different from LEGO Architecture or non-IP Icons sets. Architecture rises immediately after retirement and holds. With licensed Marvel sets the pattern is:
- Retirement announced: brief demand spike, short-term price rise.
- First 6 months post-retirement: supply outpaces demand, price drops 10–20 percent below last RRP.
- Months 6–18 post-retirement: supply dries up, price recovers to 110–130 percent of RRP.
- After that: holds steady, or a new film/series announcement pushes it back down temporarily.
Exception: unique minifig sets with no announced successor (the X-Mansion). Those follow the Architecture pattern — rising immediately after retirement.
Smaller displays
Four smaller retiring sets are worth having as displays, but none are urgent:
- 76297 Dancing Groot (459 pieces): fun Guardians display, but not rare within its sub-genre.
- 76327 Iron Man MK4 Bust (436 pieces): bust-format display. A niche audience will seek it post-retirement.
- 76329 Miles Morales’ Mask (487 pieces): mask display comparable to earlier Spider-Man and Venom masks. Second-hand expectation: moderate.
- 76316 Fantastic Four vs. Galactus (427 pieces): Galactus as a build figure. With Fantastic Four now in the MCU, a successor seems likely — no urgency.
When to buy
| Period | Situation | Advice |
|---|---|---|
| Now (May 2026) | Wide availability, price at or just below RRP | X-Mansion: buy. Rest: set alerts. |
| Q3 2026 (July–September) | First noticeable price drops | Quinjet, Civil War, Endgame become attractive. |
| Q4 2026 (Black Friday) | Deepest prices, highest stock risk | Last reliable buying window for Avengers Saga sets. |
| Post-retirement | Second-hand only, 50–150 percent above RRP | X-Mansion: expect a fast rise. Oscorp: might briefly dip below RRP. |
My pick in 30 seconds
X-Mansion without hesitation. The Age of Ultron Quinjet and Civil War Battle if you want to close out the Avengers Saga — but Black Friday is a realistic wait. Skip the Oscorp, or pick it up 6 months after retirement on the dip. The small displays if you like them, but none justify a rushed decision.
Set a BricksDeal price alert on the sets you’re considering via the LEGO Marvel theme page.
About retirement signals
There is no official LEGO retirement date. The signals come from: disappearance from the active assortment on lego.com, falling stock at Bol.com and Intertoys without replenishment, and absence from the printed LEGO catalogue. Based on those patterns, the sets above have been flagged as 2026 retirement candidates. Historical second-hand patterns are based on observations from 2020–2025.

Best for each buyer type
The four Marvel sets from this wave where you need to decide now — from genuine panic buy to calm wait.
X-Men: The X-Mansion
First large LEGO X-Men HQ ever, with seven exclusive minifigs — this one rises immediately after retirement, not after six months.
Avengers: Age of Ultron Quinjet
Recognisable Avengers set for any Marvel fan, widely available into deep Q3 2026 — no real rush, but not infinite patience either.
MARVEL Logo & Minifigures
Marvel logo as a build object with a range of iconic figures — compact display format that holds its value steadily after retirement.
Spider-Man vs. Oscorp
Norman Osborn in civilian form is only in this set — wait for the post-retirement dip if you only want it for the minifig.
