There are many important moments in the story, but the most crucialâ€”called â€œstory spotlightsâ€â€”are shown on cards. These cards have the Planeswalker symbol in their text box; this symbol has no effect on gameplay. You can read more about these events in the official Magic fiction at http://www.mtgstory.com.
The target opponent chooses whether to have Piaâ€™s Revolution deal 3 damage to them as its ability resolves. You wonâ€™t return the card to your hand if that player chooses to be dealt damage or if the card leaves the graveyard before the ability resolves.
It doesnâ€™t matter who controlled the artifact when it was put into your graveyard. Piaâ€™s Revolutionâ€™s ability will trigger if you own that artifact.
If there are no legal targets for Piaâ€™s Revolutionâ€™s ability (perhaps because each of your opponents has hexproof), it will be removed from the stack with no effect. No one may choose to be dealt damage and you wonâ€™t return the artifact card to your hand.
If a nontoken artifact is put into your graveyard at the same time as Piaâ€™s Revolution, Piaâ€™s Revolutionâ€™s ability triggers.
