The Marvel Snap Mordred card is the Series 4 reward for Sanctum Showdown in the Knights of Avalon season. The limited-time mode is scheduled for 5 – 12 November 2026, ending at the game’s server reset on 12 November. Mordred is not a Premium Season Pass unlock or one of the weekly Series 5 SNAP Pack cards.
If you’re trying to earn Mordred, the first thing to check is the reward track in your current game. The official season announcement confirms where the card is earned but doesn’t specify how many points, matches or wins it takes. This is especially important on 12 November, because the event is due to end today.
Marvel Snap Mordred card ability explained

Mordred’s Ongoing text reads: “+2 Power for each higher-Cost card here.” The wording is short, but it makes the basic plan clear. Put Mordred in a location with higher-Cost cards and he can gain Power from the cards that qualify.
One detail deserves care: the text says card here, not your card here. Don’t assume the ability counts only your side without checking how the current client handles the interaction. And don’t count expensive cards at other locations; the card explicitly says “here.”
The Marvel Snap Mordred card is an Ongoing card, so the board can affect his bonus as the match changes. Moving or removing a qualifying card, or disabling Mordred’s Ongoing ability, can alter his Power. That’s why a screenshot of one successful lane isn’t a reliable fixed calculation for every game.
How to unlock the Marvel Snap Mordred card in Sanctum Showdown

The confirmed route for the Marvel Snap Mordred card is the Sanctum Showdown limited-time event reward track. To check how close you are, open the mode in the game, inspect its rewards and look for the Mordred milestone. The live screen should also show your remaining progression and any deadline information.
Second Dinner did not include an exact Mordred milestone or a required number of wins in its season announcement. Rather than give you an invented number, the useful advice is to check the actual reward screen before deciding how many more matches you need to play.
Sanctum Showdown runs from Thursday 5 November until Thursday 12 November at server reset. That is an event window, not a guarantee that you can keep playing all evening on the last date. If you see the event marked ended in your client, you should treat the earning window as closed.
There’s a difference between an event’s matches and a shop that might remain available afterward. A lingering shop does not mean you can still make progress toward a reward track. Follow the in-game event status rather than assuming one extends the other.
How to build around the Marvel Snap Mordred card
A Mordred deck wants a sensible plan for playing higher-Cost characters at the right location. Since the effect counts cards at Mordred’s own location, the arrangement matters just as much as including expensive cards in the deck.
Start by thinking about turns rather than trying to name a supposedly perfect twelve-card list. When can you play Mordred? Which higher-Cost characters can join him in a later turn? And what are you using to fight for the other two locations? If you overinvest in one lane, a nice-looking Power total can still lose the match.
Cost reduction can complicate the Marvel Snap Mordred card’s bonus. A card’s Cost and Power are different numbers; lowering its Cost doesn’t increase Mordred’s Power on its own. Confirm unfamiliar Cost-based interactions in the game rather than relying on assumptions made before a balance change.
How Mordred differs from other Avalon cards
Lancelot rewards cards with increased Power, whereas the Marvel Snap Mordred card cares about higher-Cost cards at his location. Arthur Pendragon’s Excalibur gives your cards costing four or more extra Power. These effects can be considered together, but they don’t have interchangeable requirements.
The other Series 4 limited-time reward announced for the month is Knight’s Vow. That one is tied to Draft from 19 November to 1 December, not this week’s Sanctum Showdown run. The shared Knights of Avalon theme doesn’t mean the same activity unlocks both cards.
Can you get Mordred after 12 November?
Second Dinner’s announcement confirms the 5 – 12 November Sanctum Showdown event, but it does not promise an immediate alternative unlock route after it closes. There may be acquisition changes later, yet there is no reason to pretend the current announcement confirms a specific replacement schedule.
For now, the Marvel Snap Mordred card is a limited-time reward. Check your in-game track while the mode is still live, claim any available rewards and pay attention to the 12 November server-reset cutoff. If the event has ended, don’t follow outdated instructions telling you to queue into it anyway.
