/**
*
* You may exchange control of Perplexing Chimera and any spell cast by an
* opponent, not just one with targets.
*
* You make the decision whether to exchange control of Perplexing Chimera and
* the spell as the triggered ability resolves.
*
* If Perplexing Chimera leaves the battlefield or the spell leaves the stack
* before the triggered ability resolves, you can't make the exchange.
*
* Neither Perplexing Chimera nor the spell changes zones. Only control of them
* is exchanged.
*
* After the ability resolves, you control the spell. Any instance of "you" in
* that spell's text now refers to you, "an opponent" refers to one of your
* opponents, and so on. The change of control happens before new targets are
* chosen, so any targeting restrictions such as "target opponent" or "target
* creature you control" are now made in reference to you, not the spell's
* original controller. You may change those targets to be legal in reference to
* you, or, if those are the spell's only targets, the spell will be countered
* on resolution for having illegal targets. When the spell resolves, any
* illegal targets are unaffected by it and you make all decisions the spell's
* effect calls for.
*
* You may change any of the spell's targets. If you change a target, you must
* choose a legal target for the spell. If you can't, you must leave the target
* the same (even if that target is now illegal).
*
* Gaining control of a spell and changing its targets won't cause any heroic
* abilities of the new targets to trigger.
*
* If you gain control of an instant or sorcery spell, it will be put into its
* owner's graveyard as it resolves or is countered.
*
* In some unusual cases, you may not control Perplexing Chimera when its
* triggered ability resolves (perhaps because the triggered ability triggered
* again and resolved while the original ability was on the stack). In these
* cases, you can exchange control of Perplexing Chimera and the spell that
* causes the ability to trigger, even if you control neither of them. If you
* do, you'll be able to change targets of the spell, not the spell's new
* controller.
