Umr-Fyra, Wielder of the Key of Chaos/Rulings


 * Umuru=Fyra, Wielder of the Key of Chaos's ability will only affect SIGNI  abilities that can only be used while in the trash, such as Code Anti Nebra.
 * If Umuru=Fyra's causes the cost of a SIGNI's  ability in the trash to become 0, and that SIGNI is somehow played onto the field without using its own  ability, that S0IGNI's  ability will no longer be 0 and return to its original cost.


 * You may still use Umuru=Fyra, Wielder of the Key of Chaos|s first ability even if you only have 2 or less cards remaining in your deck. In this case, send the rest of your deck to the trash. After that, refresh your deck.
