About Expansion Algorithm
Expansion Algorithm, Sorcery, designed by Serena Malyon first released in april 2026 in the set Secrets of Strixhaven Commander and was printed exactly in 2 different ways. It's currently being selled by the minimum price of 18,64.
A card like **Expansion Algorithm** (XUU, sorcery, proliferate X times) would best fit in decks built around heavy counter synergies—such as +1/+1 counter decks (e.g., Simic or Hardened Scales strategies), planeswalker “Superfriends” decks that want to rapidly increase loyalty, poison/toxic or infect decks aiming to close out via poison counters, or Commander decks built around experience, energy, or other scalable counters. It scales especially well in slower, big-mana Commander environments where dumping large amounts of mana into X can create explosive turns. However, in most competitive formats it would likely be too slow and mana-intensive compared to more efficient proliferate options like **Tezzeret’s Gambit**, **Contentious Plan**, **Experimental Augury**, or repeatable engines such as **Inexorable Tide** or **Flux Channeler**, which provide better rate or ongoing value. While Expansion Algorithm could be powerful as a late-game finisher in casual or Commander counter-focused d
Rules
20/03/2026
If a player or permanent has more than one kind of counter on it, and you choose for it to get additional counters, it must get one of each kind of counter it already has. You can't have it get just one kind of counter it already has and not the others.
20/03/2026
If you proliferate multiple times, you don't have to choose the same set of players and/or permanents to get additional counters each time.
20/03/2026
Players can respond to a spell or ability whose effect includes proliferating. Once that spell or ability starts to resolve, however, and its controller chooses which permanents and players will get new counters, it's too late for anyone to respond.
20/03/2026
When you proliferate, you can choose any permanent that has a counter, including ones controlled by opponents. You can choose any player who has a counter, including opponents. You can't choose cards in any zone other than the battlefield, even if they have counters on them.
20/03/2026
While proliferating multiple times, players can't respond between proliferating the first time and proliferating the second time, and so on.
20/03/2026
You don't have to choose every permanent or player that has a counter—only the ones you want to add counters to. Since "any number" includes zero, you don't have to choose any permanents at all, and you don't have to choose any players at all.
