How it works
Cast Fractured Identity by paying 3, exiling Maskwood Nexus and causing each opponent to create a token copy of it.
Cast Suleiman's Legacy by paying . When it enters, its first ability triggers, destroying all Djinns and Efreets. Due to each opponent's Maskwood Nexus, this will result in all their creatures being destroyed.
Whenever an opponent has a creature enter, Suleiman's Legacy's second ability will trigger, destroying that creature.
By casting Fractured Identity on your own Maskwood Nexus, you hand every opponent a token copy that quietly turns all of their creatures into Djinns and Efreets through the Nexus's passive all-types ability. Once you follow up with Suleiman's Legacy, its enter-the-battlefield trigger immediately wipes out this newly minted army because every creature they control now matches the forbidden types. Better yet, Suleiman's Legacy remains on the battlefield to automatically destroy any future creature your opponents try to cast or create, locking them out of the game entirely.
