76218 Sanctum Sanctorum is based on Doctor Strange in the Multiverse of Madness and Avengers: Infinity War, though there are a few improvements you can make with recent and currently available sets to help represent those films or expand the overall scope of the model.
4 – 76205 Gargantos Showdown
76205 Gargantos Showdown is the only other Doctor Strange in the Multiverse of Madness and the only set to include a minifigure of America Chavez, a character who plays a huge role in the movie.
Not only can you complete the roster of Doctor Strange in the Multiverse of Madness minifigures with this set, but a portion of Gargantos is included in 76218 Sanctum Sanctorum, offering an opportunity to depict a more complete encounter between him and the heroes.
3 – 76185 Spider-Man in the Sanctum Workshop
Though 76218 Sanctum Sanctorum isn’t based on Spider-Man: No Way Home, it’s not hard to recreate scenes from that film using the set and the movie’s only model will help with that.
76185 Spider-Man in the Sanctum Workshop includes enough elements and minifigures to improve the rear room of the larger set with additional details and act out MJ’s reaction to the magical building and meeting with Doctor Strange in minifigure form.
2 – 10278 Police Station
Any of the official modular buildings could fit into this slot but we’ve chosen 10278 Police Station for how closely its design resembles the streets of New York.
Adding an extra building alongside 76218 Sanctum Sanctorum provides more room for battles, references and whatever else you might not be able to find room for on the singular baseplate included in 76218 Sanctum Sanctorum.
1 – 71031 Marvel Studios
Unfortunately, 71031 Marvel Studios is no longer available on LEGO.com, which is a shame considering it includes a more detailed minifigure of the Scarlet Witch than the version in 76218 Sanctum Sanctorum.
Those who already have or can track down this minifigure can combine the Scarlet Witch minifigures to create a more detailed version of the character, adding an extra touch of accuracy to the huge LEGO Marvel model.
