Enchantement
Quand un joueur joue un sort, sacrifiez l'Immobilisation. Si vous faites ainsi, chacun des adversaires de ce joueur pioche trois cartes.
It only works once. If someone casts another spell after it triggers, but before that trigger resolves, then it will trigger again. The first time one of these triggers resolves, it will be sacrificed for the full effect. Any additional triggers on the stack will do nothing when they resolve because you will be unable to sacrifice it additional times.
