409.1b. If the spell or ability is modal (uses the phrase "Choose one -," "Choose two -," "Choose one or both -," or "[specified player] chooses one -"), the player announces the mode choice. If the player wishes to splice any cards onto the spell (see rule 502.40), he or she reveals those cards in his or her hand. If the spell or ability has a variable mana cost (indicated by {X}) or some other variable cost, the player announces the value of that variable at this time. If the spell or ability has alternative, additional, or other special costs (such as buyback, kicker, or convoke costs), the player announces his or her intentions to pay any or all of those costs (see rule 409.1f). You can't apply two alternative methods of playing or two alternative costs to a single spell or ability. If a cost includes hybrid mana symbols in its cost, the player announces the nonhybrid equivalent cost he or she intends to pay. Previously made choices (such as choosing to play a spell with flashback from his or her graveyard or choosing to play a creature with morph face down) may restrict the player's options when making these choices.	409.1b.
