 ## Basic leaderless battle announcement — 29 October 2026
 
+In fresh classic Basic games without Harkonnen, a publicly unavailable living
+leader pool containing at least one dead leader now opens a neutral pre-leader
+preparation for that combatant, independent of their private hand. An unaffected
+opponent is already ready. The player can use Ghola from their hand or continue;
+after battle powers resolve, an inability is announced before either plan. If a
+later public Ghola revival changes the available leader, the current notice is
+withdrawn and a correction logged; already sealed plans stay sealed. This is a
+provisional online timing composition, not a publisher ruling. Captures and other
+faction/module combinations remain open.
