Pir's Whim

Players can’t take actions in between the time that friends perform their actions and the time that foes perform theirs. If any abilities trigger from friends performing actions, those triggers won’t be put onto the stack until the foes perform their actions and the spell finishes resolving.

You may call a player a friend or a foe even if that player will be instructed to perform an impossible action. For example, for Regna’s Sanction, a foe may control no untapped creatures.

When Pir’s Whim resolves and your foes perform their actions, first the next foe in turn order (or, if it’s a foe’s turn, that foe) chooses an artifact or enchantment they control, then each other foe in turn order does the same, then all chosen permanents are sacrificed at the same time. Foes will know choices made by earlier players when making their choices.

You make this choice for yourself as well as each other player. In some rare cases, you may wish to call yourself (or your teammate in a Two-Headed Giant game) a foe. You can do that.
