  The last ability triggers when the Incarnation is put into its owner's graveyard from any zone, not just from on the battlefield.
• 2007-10-01
  Although this ability triggers when the Incarnation is put into a graveyard from the battlefield, it doesn't *specifically* trigger on leaving the battlefield, so it doesn't behave like other leaves-the-battlefield abilities. The ability will trigger from the graveyard.

  If the Incarnation had lost this ability while on the battlefield (due to Lignify, for example) and then was destroyed, the ability would still trigger and it would get shuffled into its owner's library. However, if the Incarnation lost this ability when it was put into the graveyard (due to Yixlid Jailer, for example), the ability wouldn't trigger and the Incarnation would remain in the graveyard.

  If the Incarnation is removed from the graveyard after the ability triggers but before it resolves, it will remain in its new zone when its owner shuffles his or her library. Similarly, if a replacement effect has the Incarnation move to a different zone instead of being put into the graveyard, the ability won't trigger at all.
