Antes dos Spoilers no Mythic Invitational uma conversa no MTG salvation mostrou diversos planinautas ainda não apresentados da nova edição Guerra da Centelha. Acredito que o vazamento é real, porque inclui cartas que foram confirmadas como

Ajani, Jace e Liliana

e o flavor de Nicol Bolas faz sentido. Para quem não consegue ler a imagem e quer saber dos outros planinautas:
