Now, as you may or may not know, Avenger of Zendikar fills one of the reprint slots in the Duel Deck, which means it isn't (necessarily) coming back and it isn't legal for Standard play. However, the monster staring back at the Avenger is most certainly new, and will be Standard legal when Battle for Zendikar is released. I give you, Oblivion Sower:
Au fait il dit presque explicitement qu'Avenger ne sera PAS réédité.
Par contre ça ne dit pas si oui ou non on aura de nouveau du toucheterre.
