Siphon Insight

Look at the top two cards of target opponent's library. Exile one of them face down and put the other on the bottom of that library. You may play the exiled card for as long as it remains exiled, and you may spend mana as though it were mana of any color to cast that spell.

Mira las dos primeras cartas de la biblioteca del oponente objetivo. Exilia una de ellas boca abajo y pon la otra en el fondo de esa biblioteca. Mientras la carta exiliada permanezca exiliada, puedes mirarla, jugarla y usar maná como si fuera maná de cualquier color para lanzar ese hechizo.
