+ * 702.146. Disturb
+ * <p>
+ * 702.146a Disturb is an ability found on the front face of some transforming double-faced cards
+ * (see rule 712, “Double-Faced Cards”). “Disturb [cost]” means “You may cast this card
+ * transformed from your graveyard by paying [cost] rather than its mana cost.” See
+ * rule 712.4b.
+ * <p>
+ * 702.146b A resolving transforming double-faced spell that was cast using its disturb
+ * ability enters the battlefield with its back face up.
