/**
* 702.165. Backup
* <p>
* 702.165a Backup is a triggered ability. “Backup N” means “When this creature enters the battlefield,
* put N +1/+1 counters on target creature. If that’s another creature, it also gains the non-backup
* abilities of this creature printed below this one until end of turn.” Cards with backup have one or more
* abilities printed after the backup ability. (Some cards with backup also have abilities printed before
* the backup ability.)
* <p>
* 702.165b If a permanent enters the battlefield as a copy of a permanent with a backup ability or a token
* is created that is a copy of that permanent, the order of abilities printed on it is maintained.
* <p>
* 702.165c Only abilities printed on the object with backup are granted by its backup ability. Any abilities
* gained by a permanent, whether due to a copy effect, an effect that grants an ability to a permanent, or an
* effect that creates a token with certain abilities, are not granted by a backup ability.
* <p>
* 702.165d The abilities that a backup ability grants are determined as the ability is put on the stack.
* They won’t change if the permanent with backup loses any abilities after the ability is put on the stack
* but before it resolves.
