* 702.70. Champion
*
* 702.70a Champion represents two triggered abilities. "Champion an [object]" means
* "When this permanent enters the battlefield, sacrifice it unless you exile another
* [object] you control" and "When this permanent leaves the battlefield, return the
* exiled card to the battlefield under its owner's control."
*
* 702.70b The two abilities represented by champion are linked. See rule 607, "Linked Abilities." #
*
* 702.70c A permanent is "championed" by another permanent if the latter exiles
* the former as the direct result of a champion ability. #
