Enchantement légendaire : passé
Les créatures Commandant que vous possédez ont « Le premier sort de dragon que vous lancez à chaque tour coûte
de moins à lancer. »
If a card refers to a commander creature you own, a Background won't usually be counted or included for that effect. If another spell or ability causes your Background to become a creature, however, it will be included. Any effect that refers to your commander or a commander you own or control without specifying creature will apply to a Background that is your commander, as appropriate.
