Related Rules
Some keyword abilities, such as equip and modular, represent targeted activated or triggered abilities, and some keyword abilities, such as mutate, cause spells to have targets. In those cases, the phrase “target [something]” appears in the rule for that keyword ability rather than in the ability itself. (The keyword’s reminder text will often contain the word “target.”) See rule 702, “Keyword Abilities.”
Mutate
Mutate appears on some creature cards. It represents a static ability that functions while the spell with mutate is on the stack. “Mutate [cost]” means “You may pay [cost] rather than pay this spell’s mana cost. If you do, it becomes a mutating creature spell and targets a non-Human creature with the same owner as this spell.” Casting a spell using its mutate ability follows the rules for paying alternative costs (see 601.2b and 601.2f–h).
One keyword causes an object to merge with a permanent. See rule 702.140, “Mutate.”
Rulings
You don't choose a target for Yuna's Whistle at the time you cast it. Rather, a second "reflexive" ability triggers when you reveal a creature card this way. You choose a target for that ability as it goes on the stack. Each player may respond to this triggered ability as normal.
If the revealed card has {X} in its mana cost, X is 0 for the purpose of determining its mana value.
