When Windshaper Planetar enters the battlefield during the declare attackers step, for each attacking creature, you may reselect which player or planeswalker that creature is attacking.

If an ability targets something controlled by the “defending player” of an attacking creature and the defending player for that creature changes before that ability resolves, the ability won't resolve because its target has become illegal.

If you reselect which player or planeswalker an attacking creature is attacking, that creature is still considered to have attacked the player or planeswalker as declared, but it is now attacking the new player or planeswalker.

Reselecting which player or planeswalker a creature is attacking doesn't cause “whenever this creature attacks” abilities to trigger.

Reselecting which player or planeswalker a creature is attacking ignores all requirements, restrictions, and costs associated with attacking.

You may cast Windshaper Planetar outside of a declare attackers step. If Windshaper Planetar enters the battlefield outside of a declare attackers step, its ability simply doesn't trigger.
