How Do Infinity Splits Work in Marvel Snap?

Infinity Splits are Marvel Snap's card visual upgrade system. They let you customize the look of your cards with unique cosmetic finishes and flares, making every player's collection one of a kind. Splits are purely cosmetic and do not affect gameplay or card stats in any way.

How Card Upgrades Work

Every card starts at Common rarity and can be upgraded through 7 tiers: Common, Uncommon, Rare, Epic, Legendary, Ultra, and Infinity. Each upgrade costs boosters (earned by playing the card in matches) plus credits. A full cycle from Common to Infinity costs 155 boosters and 1,525 credits, producing 31 Collection Levels along the way. The credit breakdown per tier is: Common to Uncommon (25), Uncommon to Rare (100), Rare to Epic (200), Epic to Legendary (300), Legendary to Ultra (400), and Ultra to Infinity (500). Once a card reaches Infinity, it becomes eligible to split.

Finishes, Flares, and the Split Roll

Splitting resets a card back to Common but permanently adds a cosmetic effect. Split effects come in two categories. Finishes (also called surfaces) change the card's background look. Families include Rays (6 color variants), Metallic (Copper, Foil, Steel, Gold), Prism (Base, Black, Gold, Gilded), Glass (Frosted, Circuits, Wakandan), plus standalone finishes like Gold, Ink, Cosmic, Psychedelic, and Refraction. Flares (also called reveals) add particle effects when you play the card. Families include Stardust, Glimmer, Krackle, Tone, and Embers (each with multiple color variants), plus standalone flares like Confetti, Neon Trails, Snowflakes, Bubbles, and Gold Diamond. Your first split awards only a finish. Subsequent splits award both a finish and a flare. The combination is random each time, weighted by a two-phase roll: a 10% chance for a premium combo (Ink or Gold finish paired with Krackle flare) and a 90% standard roll from tiered rarity pools.

Split Protection and Mastery Interaction

Second Dinner has published official split rates at marvelsnap.com. The system includes protection against duplicate splits for a given card, so you will not receive the exact same finish+flare combination twice on the same card. Ink, Gold, and Krackle have boosted drop rates that fluctuate with game patches. Your Character Mastery level also influences the odds: higher mastery unlocks rarer cosmetic tiers in the standard roll pool, but the premium combo rate stays at a flat 10% regardless of level. Each split also grants 15 Mastery XP toward that card.

Tracking Splits on SnapComplete

The Splits page shows every split you have earned across your entire collection. Filter by specific finishes, flares, and borders, or use the quality tier filter to find all your cards at a particular rarity. Sort by split count, mastery level, mastery rank, most recent split, or number of owners. The Split Timeline view (premium) gives a chronological stream of every split event with the exact finish and flare received. Per-card split rankings are available on the Card Leaderboards, where you can see how your split count stacks up against other tracked players.

What Does a Full Split Cycle Cost?

Each split takes your card from Common all the way back through the 7 upgrade tiers to Infinity again. The booster and credit cost for one complete cycle:

That's 155 boosters and 1,525 credits for each split. If you want to split a card 10 times for a full collection of finishes and flares, you're looking at 1,550 boosters and 15,250 credits for that single card. Credits are usually the bottleneck since boosters accumulate passively from playing the card, while credits are a shared resource across your entire collection. Each upgrade step also grants Collection Levels, so splitting is one of the primary ways to progress through the CL track. A single split cycle generates 31 Collection Levels worth of upgrades.

Which Cards Should You Split First?

Split cards you actually play. Boosters are earned by playing the card in matches. If you're trying to split a card that never makes it into your decks, you'll be waiting a long time to stockpile 155 boosters. Focus on cards that show up in multiple decks or are evergreen staples. Prioritize cards that stay on the board. Some cards get played face-down or fire an On Reveal and barely stick around. Ongoing powerhouses and game-ending plays sit on the board for several turns, giving your opponent plenty of time to see your splits. Think about the card's art. Darker backgrounds make Metallic and Gold finishes pop. Lighter art works better with Prism and Glass. Consider the meta. If a card gets nerfed, you might stop playing it, and those boosters are locked in. That said, splits are permanent and still look great in your collection even if you bench the card.

How Do Finishes and Flares Differ?

Finishes (sometimes called surfaces) change the card's visual texture, from subtle shimmers to completely different art styles. Second Dinner's four base finishes, Foil, Prism, Ink, and Gold, are the default pool every card can roll. Additional finishes like Refraction, Metallic Gold, and Fire are added to a specific card's roll pool once its Character Mastery track reaches the corresponding level milestone. Flares (sometimes called reveals) are particle animations that trigger when you play the card. They only affect the reveal moment, not how the card looks in hand or on the board. The four base flares are Glimmer, Tone, Stardust, and Krackle, and Mastery milestones plus randomized Mastery Cache rewards expand the flare pool on a per-card basis. Your first split on any card only awards a finish. Every split after that awards both a finish and a flare.

What Are the Rarest Splits?

Starting with the 4th split, the roll uses a two-phase system. First, a 10% premium roll is checked. If it hits, you get a premium combo: either an Ink or Gold finish paired with a Krackle flare. These are the combos you see people showing off on social media. Splits 1-3 can't roll the premium combo. If the premium roll doesn't hit (90% of the time), you get a standard roll from that card's current finish and flare pool. Second Dinner has noted that Ink, Gold, and Krackle carry boosted weights that fluctuate with game patches, though the exact per-cosmetic drop rates aren't published. The system includes duplicate protection, so you'll never get the exact same finish plus flare combination twice on the same card. Character Mastery level also factors in: higher mastery on a specific card unlocks rarer cosmetic tiers in the standard roll pool.

How Does Splitting Interact with Mastery XP?

Every split earns 15 Mastery XP toward that specific card. Mastery is a 30-level per-card progression system. The only XP sources are Infinity Splits (15 XP each) and variant ownership (25-250 XP depending on rarity). Playing the card earns boosters, not mastery XP. The loop works out well: playing a card earns boosters for splitting, splitting earns mastery XP, and higher mastery unlocks rarer split results. Owning more variants of the card also pushes your mastery level up, which improves your cosmetic odds. See the Mastery XP FAQ for the full breakdown.

Common Misconceptions About Splits

"Splits affect card power." They don't. A 10-split Ink Krackle card has exactly the same stats and abilities as a base Common card. Splits are 100% cosmetic. "You lose the card when you split." Your card resets to Common rarity, but you keep the card itself. You just need to upgrade it back to Infinity to split again. The finish and flare from each split are permanently saved. "You can choose your finish and flare." The roll is random. You can influence odds through mastery level, and duplicate protection means you won't get the same combo twice, but you can't pick a specific finish or flare. "Splitting is wasteful if you don't have all the cards." Depends on your priorities. Credits spent on splits could go toward Collection Level upgrades to earn more cards from Collector's Reserves. But if you're past the CL track or just care more about cosmetics than completion, split away.
