* 702.102. Bestow
*
* 702.102a Bestow represents two static abilities, one that functions while the
* card with bestow is on the stack and another that functions both while it's
* on stack and while it's on the battlefield. "Bestow [cost]" means "You may
* cast this card by paying [cost] rather than its mana cost." and "If you chose
* to pay this spell's bestow cost, it becomes an Aura enchantment and gains
* enchant creature. These effects last until one of two things happens: this
* spell has an illegal target as it resolves and or the permanent this spell
* becomes, becomes unattached." Paying a card's bestow cost follows the rules
* for paying alternative costs in rules 601.2b and 601.2e-g.
*
* 702.102b If a spell's controller chooses to pay its bestow cost, that player
* chooses a legal target for that Aura spell as defined by its enchant creature
* ability and rule 601.2c. See also rule 303.4.
*
* 702.102c A spell's controller can't choose to pay its bestow cost unless that
* player can choose a legal target for that spell after it becomes an Aura
* spell.
*
* 702.102d As an Aura spell with bestow begins resolving, if its target is
* illegal, the effect making it an Aura spell ends. It continues resolving as a
* creature spell and will be put onto the battlefield under the control of the
* spell's controller. This is an exception to rule 608.3a.
*
* 702.102e If an Aura with bestow is attached to an illegal object or player,
* it becomes unattached. This is an exception to rule 704.5n.
*
* You don't choose whether the spell is going to be an Aura spell or not until
* the spell is already on the stack. Abilities that affect when you can cast a
* spell, such as flash, will apply to the creature card in whatever zone you're
* casting it from. For example, an effect that said you can cast creature
* spells as though they have flash will allow you to cast a creature card with
* bestow as an Aura spell anytime you could cast an instant.
*
* On the stack, a spell with bestow is either a creature spell or an Aura
* spell. It's never both.
*
* Unlike other Aura spells, an Aura spell with bestow isn't countered if its
* target is illegal as it begins to resolve. Rather, the effect making it an
* Aura spell ends, it loses enchant creature, it returns to being an
* enchantment creature spell, and it resolves and enters the battlefield as an
* enchantment creature.
*
* Unlike other Auras, an Aura with bestow isn't put into its owner's graveyard
* if it becomes unattached. Rather, the effect making it an Aura ends, it loses
* enchant creature, and it remains on the battlefield as an enchantment
* creature. It can attack (and its {T} abilities can be activated, if it has
* any) on the turn it becomes unattached if it's been under your control
* continuously, even as an Aura, since your most recent turn began.
*
* If a permanent with bestow enters the battlefield by any method other than
* being cast, it will be an enchantment creature. You can't choose to pay the
* bestow cost and have it become an Aura.
*
* Auras attached to a creature don't become tapped when the creature becomes
* tapped. Except in some rare cases, an Aura with bestow remains untapped when
* it becomes unattached and becomes a creature.
