Card synergy
Some cards work better together than their individual records suggest. This compares a pair's win rate against what its two cards manage on their own, in the same decks.
Read this as a hint, not a finding. Cards are not assigned to decks at random, so a pair can look strong because it appears in strong decks, because both cards suit the same archetype, or because stronger players favour it. The comparison narrows that question. It does not settle it.
Scoped to August 2026 balance changes. 510 pairs qualified: each appears in at least 3 established decks with 100+ battles. Only pairs whose interval separates them from their own expected rate are ranked, so the order is not driven by small samples. How we count.

Worse together
These pairs won less than their two cards manage separately. Often a sign the two want different game plans, or compete for the same elixir.
