Best Bastion Decks and Strategy Guide

Bastion is the third Series 5 cards joining Marvel Snap for the September 2025 Season, Visions of the Future. It is a 4-Cost, 3-Power card that reads: On Reveal: Add copies of your other cards here to your hand. Set their Costs to 2 and Power to 3.

Today, let’s explore the new card strengths and, of course, the best decks to try it out in.

Series 5 cards can be purchased for 6,000 Collector’s Tokens from the Token Shop as the latest Seasonal Spotlight card. They will be also be included in the Seasonal Series 5 Snap Pack for 5,000 Collector’s Tokens during their season and the following one.

Strengths and Weaknesses

Immediately, we can spot how low Bastion’s power is. Three for a 4-cost is half what Wiccan is working with, meaning Second Dinner must have a lot of faith in Bastion’s ability.
Honestly, I can’t fault them, as the new card has immediate synergies with one of the top archetypes in the game at the moment : Iron Hand.

That deck loves to copy cards with Frigga and Moon Girl. Now, Bastion represents another way to do so. It might actually be the strongest card for the job, since it will copy multiple cards just like Moon Girl, but also allow us to get them on the board and target the ones we want to copy, like Frigga.

Once Victoria Hand hits the board to give our created cards a bonus 2 power, and those created by Bastion only cost one energy thanks to Quinjet. I’m sure the power of Bastion will be crystal clear.

Even if we ventured outside that precise archetype, there are other synergies to consider with Bastion. Indeed, there is another part of Bastion we have to discuss : Copied cards are now [2/3].

First up are cards with low power, which would benefit from growing to 3-power. Certain 1-costs are strong enough to cost one more energy and still be good, while many 3-cost cards would become much more powerful once copied by Bastion.

We could even take it up a notch, and look to play high cost cards on turn four, using Wave for example, and then copy those cards on turn five with Bastion.

Even more complicated, but through using Luna Snow or Wave to get Sera on the board on turn four, we can play Bastion alongside any 3-cost we like on turn five. Perfect to copy the likes of Silver Surfer, Patriot or Cerebro, the same way we would play Victoria Hand and Frigga together on turn five in an Iron Hand deck.

Last, Bastion could also be paired with high power cards we want more copies of. In order to restore their power once they transformed into a 2-cost, we could use Shadow King or Luke Cage, just like we do with Anti-Venom.

From a power level standpoint, Bastion should not suffer too much from its low power. Typically, the card will generate power through copying our cards rather than being a threat in itself. When everything goes according to plan, I have little doubt Bastion will be able to rival some of the best 4-cost cards, such as Gwenpool, which often equal around 15 power due to the buffs landing on the right cards.

Last, Bastion could also be paired with

However, Bastion might also be fragile in the face of disruption :

Negasonic Teenage Warhead or Red Guardian could also be annoying cards to deal with, but Cosmo is the real boogeydog for Bastion. Indeed, if we start stacking our good targets in one place, the opponent will not only be able to grab priority through playing on the other two locations, they will have no doubt where to place Cosmo.
Currently, disruption isn’t very popular in Marvel Snap, but if certain decks were to become dominant because of Bastion, the metagame could change, and start packing more of those cards.

Something like this could be annoying to go up against for Bastion :

The Verdict: Should You Get Bastion ?

Becoming a staple in a top tier archetype is enough to make Bastion very popular once it releases. Yet, the card could also create some snap worthy, gimmicky patterns of play alongside high cost cards we managed to discount as well.

Overall, I feel like Bastion will be as strong as the metagame allows it to be. If there is little disruption, I can easily picture the new 4-cost joining the already great Iron Hand and turn it into the dominant archetype. However, if we decide to run some counter cards, Bastion might struggle a bit more, as the ability really is everything the card has to offer, considering the very low power it has for a 4-cost.

Pre-Release Score:

Bastion Decks

Expect to see a lot of Iron Hand soon after Bastion releases.

There are more than enough ways to get Sera on the board by turn four in Marvel Snap – Surge, Luna Snow, Esme Cuckoo, H.E.R.B.I.E… – to build a Silver Surfer deck around Bastion.

Ongoing Combo type of decks tend to be very fragile. Bastion will raise their ability to pull off crazy synergies, but won’t help with protecting our cards, except if we get to copy them before Enchantress or Red Guardian comes down.
However, Gorgon is an interesting prospect, as it could demolish an Iron Hand deck on its own if we manage to copy or boost its ability.

Apart from Surfer and Ongoing, which required a bit more tailoring. There are a good amount of decks able to simply welcome Bastion in their current top performing list :

Variants

Conclusion

Simply through its obvious synergy with Iron Hand, Bastion should have an immediate impact on the metagame, finally clearing up which is the best archetype in the game. From there, the question is whether the player base will adapt against that archetype, or look for ways to beat it with even more points.
