Spellhoard

Every spell you buy stays active.
No benching, no sideboard, no dead cards. Draft a spell and it joins the fight forever. Your whole book resolves as one escalating machine, and that machine is your build.

The loop
Draft. Build. Watch the fight resolve. Learn what beat you, and go again. Runs are short, the stakes escalate every round, and a loss teaches you something.

Eight classes that want each other
Frost, Fire, Light, Physical, Druid, Rogue, Warlock and Blood. Each has its own engine, plus dual school cards that only make sense when two of them meet. Professions compound on top. The interesting builds are the ones the game never handed you.

Your opponents are real players
The builds you fight came out of real runs. Duel a friend directly, or climb a standardised ladder that gets harder in steps you choose.

Pay once, get everything.
Every class, spell, and mode is in the box, forever. No power for money, not now and not later.

The same fight on every machine
Combat is deterministic integer maths. The same build and the same seed produce the same result anywhere. No hidden dice decide your run, and every crit is disclosed in the post fight breakdown.
