Before & After: Session Changes

See what your editing session has changed — as numbers, charts and a list you can undo.

The Session Baseline

When you open the editor, Grimoria snapshots the deck. As you edit, every analysis tab — stats, mana curve, mana fixing, synergy, combos, tokens, suggestions and the companion window — draws that snapshot as a dashed Before series behind the live data, and every count reads before → now with a +n / −n pill. An untouched deck shows nothing extra.

The Before Switch

Flip Before to view the whole deck exactly as it was when the session started. Editing is off while it is on, and a banner names the snapshot time. Back to now returns to the live list.

The Changes Tab

Once you have edited something, a Changes tab appears with the full deck impact of the session: card count, mana value, price, synergy, bracket and power level, combos gained or broken, and the lists of added and removed cards. Undo a single change from its row.

Accept or Revert

• Accept changes — Make the current deck the new baseline
• Revert to before — Put the deck back to the snapshot, through the same autosave path as any edit

The baseline survives a page reload and is kept per deck on this device. Autosave is unaffected: your edits are always saved as you go.
