4 rulings from Wizards of the Coast
- 15 July 2006You can’t exile a card from your hand to pay for itself. At the time you would pay costs, that card is on the stack, not in your hand.
- 15 July 2006If you don’t have two cards of the right color in your hand, you can’t choose to cast the spell using the alternative cost.
- 15 July 2006Paying the alternative cost doesn’t change when you can cast the spell. A creature spell you cast this way, for example, can still only be cast during your main phase while the stack is empty.
- 15 July 2006You may pay the alternative cost rather than the card’s mana cost. Any additional costs are paid as normal.
