Éphémère
Ne jouez ces Semailles que pendant votre tour.
Vous avez un tour supplémentaire après celui-ci si un adversaire a joué un sort bleu ce tour-ci.
You only get an extra turn if an opponent cast a blue spell this turn prior to this spell resolving. Note that "casting" a spell only requires it to be announced, so an unresolved spell still counts as having been cast.
