Orthogonal Diagonalizer

When this artifact enters and whenever an opponent loses the game, exile the top card of your library. You may play a land or cast a spell from among cards exiled with this artifact, and you may spend mana as though it were mana of any color to cast that spell. When you do, exile the top card of their library. Timing rules still apply. When you cast a noncreature spell from exile, create a tapped red dust token. (It’s an artifact with “{T}, Sacrifice this token: Add {R}, use this mana only to cast spells from exile.”)
