Fatecaller
Three archetypes, three difficulties, a mulligan, and a deck-building workshop where your brews fight the champions a metagame simulation evolved. The only randomness in the whole game is the shuffle, which is why the attack forecast can tell you exactly what a trade will do before you commit.

Changelog
- 2026-07-16·New name, new world: the game is now Fatecaller. Same deterministic engine and machine-certified balance, re-skinned into a fantasy of fate and foresight where the no-luck rule is the whole point. The three archetypes are now the Emberseers, the Wardens, and the Manyfold; the traps you lay face up are omens; every card was renamed to match. No luck, only who foresaw further.
- 2026-07-16·Set 8: two mechanics that reward sequencing. Overload cards hit above their cost, then dock your energy next turn, so you buy a big play now and pay for it later. Combo cards fire a bonus only when they are your second play of the turn, rewarding the aggressive chains. Certified on two seeds with all three colors reaching the crown; both mechanics adopted, and the workshop and ghost pool play them back at you.
- 2026-07-16·Set 7: Stoke, a new mechanic. Feed one of your own units to the furnace for a burst of burn, cards, or armor, and the fed unit's death effects still fire. Certified on two seeds, adopted into the meta, and it fights back in the workshop and the ghost pool. Plus a daily leaderboard and ghost matches against real players' decks.
- 2026-07-15·The engine transplant: Slagworks now runs as native TypeScript, proven bit-identical to the Godot build across 400 recorded games. Instant boot, no download. The workshop became a binder: eight named decks, autosave, and multicolor brews that fight the open meta. Local records start fresh with the new build.
- 2026-07-15·The Draft: open-color, machine-certified. Today's Mine deals everyone the same twenty offers; pilot your picks through a gauntlet of rival drafts and champions until three losses.
- 2026-07-14·Set 6: rigs, traps laid face up so you can play around them. Certified on two seeds; the workshop gauntlet now fights back with them. Plus a scrolling card browser and a simulation-backed attack forecast.
- 2026-07-14·Fatigue is now visible: empty-deck burns are named in the log and floaters, and the hero panel warns with the next burn size.
- 2026-07-14·Fixed the defeat-screen bounce: opening the workshop after a loss no longer snaps back, and the loss is only recorded once.
- 2026-07-13·The mulligan screen grew a card preview: tap a card to read its full rules text, tap again to redraw it.
- 2026-07-13·The Workshop deck editor, sets 4 and 5, the upkeep engine mechanic, concede, foe pace, win streaks.
- 2026-07-12·Animations, the mulligan, the game log, and the balance patch that finally hit every target.
- 2026-07-11·Hard mode, the card-game visual overhaul, touch fixes, and confirmation flows for plays and attacks.
- 2026-07-10·Built and balanced: twelve patches and roughly eighty thousand arena games.
