/**
* 702.32. Flashback
*
* 702.32a. Flashback appears on some instants and sorceries. It represents two
* static abilities: one that functions while the card is in a player‘s
* graveyard and the other that functions while the card is on the stack.
* Flashback [cost] means, "You may cast this card from your graveyard by paying
* [cost] rather than paying its mana cost" and, "If the flashback cost was
* paid, exile this card instead of putting it anywhere else any time it would
* leave the stack." Casting a spell using its flashback ability follows the
* rules for paying alternative costs in rules 601.2b and 601.2e–g.
