  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 · Wizards of the Coast
  If a spell or ability you control attempts to counter a spell that can't be countered, it doesn't. Since the spell wouldn't be countered, Guile's ability has no effect on it. The spell will continue to resolve normally.
• 2007-10-01 · Wizards of the Coast
  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 their 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.
• 2007-10-01 · Wizards of the Coast
  Exiling the spell is mandatory. Casting it is not.
• 2007-10-01 · Wizards of the Coast
  A spell exiled this way was never actually countered.
• 2007-10-01 · Wizards of the Coast
  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.
• 2007-10-01 · Wizards of the Coast
  Guile's second ability replaces "counter [a certain spell]" with "exile [a certain spell] and you may cast it without paying its mana cost." You have the option to cast it immediately upon its exile. If you choose not to, it remains exiled and you don't get another chance to cast it. If the spell or ability that tried to counter the spell has additional effects, it then continues to resolve.
• 2007-10-01 · Wizards of the Coast
  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.
