A deck to beat. A world left to discover.

36,912 simulated games across 262 candidate entries. Aegrix exploration with removal leads this search, using efficient Insight Allies from several factions to race for Renown while Reserve protects its board.

Strongest among these tested builds. This is a small search of a vast deck space, using two heuristic bot styles. Human play, different mulligans and unexplored combinations may change the ranking. Win score counts draws as half a win.

How we searched

Seven seed archetypes across all 18 Companions; three generations of legal 1–3 card mutations; top 12 with max two per Companion enter a full-policy round robin. Four finalists frozen before held-out testing against all 18 faction starters and all 12 elite decks, including mirrors. Both seats, first players and four policy pairs; three fresh scenarios. Inventory and JSON serialization checked after every holdout action.

Remove support-only cards from decks without Constructs, test draw/removal/movement/body replacements and twelve purpose-built precision/tempo counters across six Companions. Rank screening by score against custom decks first. Freeze four finalists, then independently test versus 18 starters, the original 12 elite custom decks and eight refined rivals. Each finalist plays 1,824 fresh games, all seats/starts/four bot policy pairs and three scenarios, with inventory/JSON checks after every action. Prior holdout is development evidence for this round.

Open Atlas uses 30 cards and an outside-deck Companion. All current available Ally, Tactic and Construct designs may mix; printed identity copy caps remain. Faction-wide Reserve and Claim belong to the selected Companion faction. Standard formats retain their faction restrictions.

Strongest among tested candidates under two heuristic bot styles, not a proof of optimal deckbuilding or human strength. Seeded weighted construction and local mutations explore a tiny fraction of legal decks. No custom mulligan policy. AI does not fully model long-term mixed-card combinations, bluffing or optimal evolution choices.

Rules update: current play allows discarding a hand card for 1 Charge during your main turn, without an immediate replacement draw. The recorded simulations on this page predate that option; its balance impact has not yet been measured.
