History in hand. Strategy across eras.
A premium historical comparison engine for collectible cards, era matchups, and deterministic play.
eracii treats every card as a key into a deeper historical record. Compare figures side-by-side, audit their pressure profiles, and browse a growing canon spanning launch and second-wave sets.
Demonstration prototype for research, pitching, and pre-commercial presentation. Final production art should be rights-cleared before any sales launch.
The Arena
PhoneArena-style card comparison for historical pressure.
Load any two figures, flip their cards for the short record, then drop them into a specific game or battlefield. Arena Shift scenarios reinterpret the matchup through deterministic house rules instead of RNG.

The Index
Search the living record.
Eracii catalogs the entirety of recorded human history. Every figure, every era, every consequence. The physical cards are just the keys; this database is the living historical index beneath them.
The Engine
Rules of Play
This prototype presents the core deterministic logic in classroom- and collector-safe language.
The Golden Rule
Eracii relies on exact, deterministic math. No dice, no coin flips, no RNG. Superior strategy and synergy win.
The Default Arena
The default baseline for all battles is the present day (). Modern icons have maximum technological and broadcast range; historical figures are stripped of their native era's infrastructure unless an Arena Shift card is played.
Hard Power vs. Soft Power
Characters attack using kinetic or military force (Hard Power) or ideological and cultural influence (Soft Power). A modern pop star's Digital Mobilization can overwhelm a 1940s dictator's Hard Power in a present-day arena.
Persistent Summons
Leaders and Icons may summon their historical Armies or Fandoms as persistent units that travel with them regardless of the temporal arena.
Request A Card
Submit a figure for the research queue.
The initial canon is wide, but the card record is built to grow. Requests are stored locally in this prototype so the workflow can be demoed before a backend exists.
