Best Sanctum Showdown Cards

Probably more important than the decks themselves, here are the cards we can spot in a lot of decks, establishing themselves as the top inclusions for Sanctum Showdown:

Amongst the Guardians of the Galaxy, these three appear to be the best cost-to-power ratio available. However, Drax and Groot are fantastic options if you were on a budget or looking for more On Reveal cards to include in your deck.

The moving werewolf is once again a remarkable card in Sanctum Showdown. Merlin giving us 1-cost on Reveal cards every turn naturally makes for a great support.

A high power 1-cost alongside a 4-cost able to move a card away are both great for Sanctum Showdown. They open for a 1-cost, 6-power card in Miles Morales so what is not to like.

The Move trio able to grow in power and follow the Sanctum Around acts as a cheaper, but more limited Werewolf by Night synergy. However, it can pair with the other Move cards above to make up for a great 6-pack.

Tier 1

Following the Sanctum around naturally favors cards able to move, or develop points flexibly. Yet, these strategies tend to require certain patterns to align, as each card on its own does not represent that much power.
The 10 Power archetype took the exact opposite road. The deck is not flexible, nor does it look to move big cards around the field. Instead, it develops a ton of points each turn wherever the Sanctum might be.

Extremely basic, but not everyone can match a 10+ power card per turn. Plus, Zabu and Surge actually give the deck that little energy cheating spice.

Potential Additions

Surge and Lizard share the slot in the 2-cost slot. Cull Obsidian can replace Ares if you missed that card.

Good & Move

The same concept dominated the previous Sanctum Showdown iteration, and except for Sauron 10 Power, this deck is repeating that feat.
Move gained Batroc the Leaper, a fantastic card to follow the Sanctum around, while Werewolf by Night remains the best card in the mode if you play it early.
Atop the curve, we have the Laufey, Gamora, Gorr trio for points. They were already great cards the previous time so no surprise here either.

The new inclusion is Mercury, which mostly serves as a counter to mirror matches. Indeed, most decks have a bit of move included, and stopping the opposite Werewolf by Night is back breaking.

Potential Additions

This is the most flexible build in the game, able to welcome a ton of different cards. I wouldn’t be surprised to see Hydra Bob, Miles Morales and Stegron in the deck, nor would Shang-Chi or such type of cards be weird either.

Tier 2

Playing with four energy when the Sanctum appears is an incredible edge. Indeed, most decks will develop 7 points at most with Groot, while many will simply play their Werewolf by Night for future turns. Arishem should be able to beat both consistently.

From there, if you can keep that edge and win the next turn as well, you should be in a strong lead points wise, and only have to close the deal for the final win.

Random cards will get in the way, which explain the lower win rate compared to the very reliable builds above. Yet, Arishem enjoyers should have a great time in Sanctum Showdown.

Potential Additions

4-cost cards are the most flexible in the deck. Vision, Ghost Spider, Doctor Strange can make sense. Otherwise, Quicksilver plus Cull Obsidian are another great duo.

Kazoo will eat you alive if you don’t get a solid start, building a commanding lead before you can get your synergies on track. However, Kazoo also lacks some flexibility, especially if it can’t build that lead in the first turns.

This is a bit of an all or nothing type of strategy. Seems to work more often than not, as well as being the easier deck to turn into a Series 3 friendly build.

Potential Additions

Star-Lord and Groot can replace cards you would be missing early, while Shang-Chi, Gamora and Onslaught can be fine late turns options.

Werewolf and Batroc the Leaper simply allow more flexible decks to do the same thing without having to build the entire deck around the move synergy.
Then, while this deck is almost impossible to stop when the draws align, Move simply feels like a more rigid way to play the Good & Move concept in Tier 1.

Potential Additions

Toxin or Frigga could make sense in this deck, bringing some Bounce elements without losing too many points in the process.

Tier 3

A few other synergies have their merit in the mode, although they tend to require more precise sequences of draws to perform. Yet, considering Sanctum Showdown is mostly played to earn rewards, might as well have fun while doing it. If you like any of these synergies, enjoy !
