2006-07-15	If an opponent casts a spell with X in its mana cost, the mana value of that spell takes the value of X into account. If you reveal a card with X in its mana cost, X is 0. For example, if your opponent casts Blaze with X=1, Counterbalance will counter that spell if you reveal a card with mana value 2, but it won't counter that spell if you reveal a Blaze of your own.
2017-04-18	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.
