When does Sanctum Showdown run next?

SnapComplete's Sanctum Showdown page pulls live schedule data from the game, so the pill at the top of the page shows the next window as soon as Second Dinner confirms it.

What rewards can you earn in Sanctum Showdown?

Sanctum Showdown uses a Charm-based economy. Every match pays Charms win or lose, and Charms spend in the Relic Shop. Pass tracks and shop stock change every run, and the tables on this page show them.

What are the best decks for Sanctum Showdown?

Strong Sanctum Showdown decks flex fast because the Sanctum location moves every turn. Movement cards, cheap reposition, and board-wide power boosts outperform slow big-finisher lists that commit to one lane early. Each run also ships its own banned list that shuts down problematic interactions. SnapComplete ranks Sanctum Showdown decks by win rate when the mode is active; the list sits below this guide.

Does every run have an Event Pass?

No. Longer runs of a week or more usually come with an Event Pass and an Event Shop. Short weekend runs of a few days usually offer only a free reward track of cosmetics, with no Event Pass. The tables on this page show what a run includes.

Marvel Snap Sanctum Showdown Guide

Sanctum Showdown is Marvel Snap's points-race LTGM. Instead of a single check at the end of the game, every location you are winning at the end of each turn pays points, and one location is the Sanctum, which pays the most. The first player to the point target wins. Match points fill the reward track, which pays Charms to spend in the Relic Shop on variants, cards, and Portal Pulls. Looking for the crossover event that pairs this scoring with Grand Arena Champions? That's Grand Arena Showdown, a separate special run. SnapComplete tracks every run. 7 Sanctum Showdown events have run since the mode launched. 130K games tracked in 3 days last run across 22K synced collections.

How Sanctum Showdown Works

Sanctum Showdown swaps Snap's normal win 2 of 3 locations rules for a points-to-16 format on the standard 3-location board. On turns 1 and 2, one random lane becomes the Sanctum and pays 1 point to whoever wins it. On turn 3 and beyond, the Sanctum pays 4 points per turn while the other two lanes pay 1 each. The Sanctum can move to an unrevealed location, so lane priority shifts fast.

Snapping works differently. Starting on turn 3, each player can snap once per turn. A snap adds +1 to the Sanctum's point value for that turn only, so if both players snap on the same turn, the Sanctum can pay 6 points. The first side to 16 total points wins, which can happen as early as turn 4.

Some runs use a variant ruleset. Variant runs are marked in the run dropdown, and picking one shows its rules beside that run's Event Pass and Shop.

Entry costs one Scroll, refunded on a win. You start with a batch of Scrolls and regenerate more on a timer, and Second Dinner sets those amounts per run, so check the in-game Scroll counter for the run you are playing. Every match pays Charms regardless of outcome, and Charms spend in the Relic Shop. The Shop table on this page lists each run's stock.
