- * charges are keyed by instance, so they travel automatically).
+ * A physical, droppable object is anything the card face marks as one —
+ * the object-typed stones, and attack/neutral cards bearing the OBJECT
+ * subtype (dagger, rock, wizardblade — "this is most certainly an object",
+ * per its FAQ — the wands, the master key, the handful of tacks). Wand
+ * charges are keyed by instance, so they travel with a traded wand.
