Aeon's End

On your turn you cycle through a fixed personal sequence — Cast spells already prepped in your breaches, Main Phase (play gem cards for aether, buy gems/relics/spells from a 9-card market, prep new spells into open breaches), Draw back to 5. The signature physical action is the 'prep, then cast next turn' beat: you place a spell card sideways into a breach this turn, and only on your NEXT turn does it actually go off — making your discard order a deliberate construction. Crucially, you NEVER shuffle your player deck: when it empties, you flip the discard pile face-down and that becomes your new deck, so the order you discard cards in determines exactly the order you'll draw them.

Setup: each player picks a breach mage (asymmetric ability + starting breach configuration), starts with a 10-card deck (gems + crystals + sparks). The shared market has 9 supply slots (3 gems, 2 relics, 4 spells) drawn from a tunable pool. Each round, draw the top of the Turn Order Deck (a small deck of player tokens + 2 nemesis tokens shuffled together) — that determines who acts next, including the possibility of back-to-back nemesis turns. Player turns: Cast prepped spells (from breaches), Main Phase (spend aether to buy/prep), Draw 5. Nemesis turns: draw a Nemesis card (Attack/Power/Minion), resolve its effect, advance any persistent threats. The nemesis (e.g., Rageborne, Crooked Mask) has 70 health; you win by reducing it to 0. You lose if Gravehold (the city, with ~30 health) reaches 0, or all mages are exhausted.

Core tradeoff: every spell prepped this turn delays its impact a full round, so you must read the nemesis's telegraphed threats and pre-position damage two beats ahead. Discard-order strategy means you choose the order you play gems vs. crystals each main phase to control next-deck-flip order — turning Aeon's End into a deck-sequencing puzzle, not a deck-shuffling lottery. The market's 9 fixed slots create a small option space per turn (typically 3-7 viable buys/preps) but the cross-player coordination space is large because breach mages have distinct roles (DPS, healer, breach-opener, support). What makes a good move hard: the variable turn order can compress nemesis turns into devastating double-acts, so risk modeling against possible turn sequences is a constant exercise.

Top skill: deck-sequencing forecasting — strong players plan the exact order their next 10-card cycle will appear and prep spells to land into known turns. Second: co-op role discipline — each mage's asymmetric ability plus opening breach pattern means the table needs an explicit damage/utility/heal split. Third: probability reading on the Turn Order Deck (tracking which player and nemesis cards remain unseen this round). Memory load is moderate; arithmetic is small (single-digit damage/aether). The 'no shuffle' rule means strong players experience deterministic combo construction, which is a different skill profile than the gambling-feeling that defines most deckbuilders.

You are a breach mage defending the last underground refuge of humanity, Gravehold, from eldritch invaders. Charge breaches, prep spells, and unleash combos to kill the Nameless before it crushes your city.

Dark, illustrative dark-fantasy — moody indigo/violet/crimson palette, gritty pen-line nemesis portraits, breach mages depicted with a Final Fantasy-meets-graphic-novel character vocabulary. Gem cards have warm orange-red art-deco frames vs. cool blues for spells; the aesthetic intentionally avoids the bright-cartoon norm of most deckbuilders, leaning into a Dark Souls / Lovecraft-adjacent identity.
