Encantamiento
Siempre que un oponente juegue un hechizo, puedes mostrar la carta superior de tu biblioteca. Si lo haces, contrarresta ese hechizo si tiene el mismo coste de maná convertido que la carta mostrada.
If an opponent casts half of a split card (for example, Hit), it won't be countered if you reveal that same split card. The mana value of a split card is determined by the combined mana cost of its two halves, but the mana value of Hit is determined using only that half's mana cost.
