Hidden Targets and New Choices

A permanent played from Hidden normally enters its original battlefield. If a specific effect permits another battlefield, its play-effect targets use where it was actually played. A hidden spell’s targets instead use where the spell was played from. Every other target requirement still applies.

Blastcone Fae played from Hidden at X normally chooses a legal unit at X for its play effect. If Last Caress lets you play it from that facedown zone to Y, that play effect must instead choose a legal unit at Y. The permit to change the unit’s destination does not let its play effect target anywhere.

An explicit targeting restriction can require a target somewhere else. That exception applies to the particular target whose restriction cannot be met at the Hidden battlefield. It does not free every target from the location limit.

The rules’ two-target example chooses a unit you control, then another unit you control at a different location. Played from Hidden at X, the first target must be at X. The second must be at a different location because its own instruction explicitly requires that. You cannot choose the first at Y and the second at Z just because the spell has one other-location choice.

An instruction choosing a unit you control at another location can qualify for the exception: it could never choose a unit at the Hidden battlefield. Choose from locations that satisfy that text. By contrast, a plain instruction choosing a unit does not acquire this exception just because the battlefield has no eligible unit.

The target rule is also not a limit on every non-targeted effect. A spell can Buff a friendly unit at its Hidden battlefield and apply a separate this-turn bonus to Buffs on friendly units elsewhere. Only the chosen target is restricted by this rule; read the scope of the remaining instructions normally.

An effect letting you make new choices does not remove the spell’s Hidden origin. Even if control of the spell changes, any new targets must satisfy its battlefield restriction and any explicit exceptions. The new controller, the player now controlling the spell, also uses its normal targeting requirements.

Worked sequence - A plays a hidden spell from X choosing A’s friendly unit there → B gains control and may make new choices → B can choose a legal friendly unit at X if one exists. B cannot move the choice to Y just because B controls Y. If choices are remade, remake the entire eligible set legally, even when choosing the same options again. Choosing not to remake any choices leaves the existing choices in their current state, including any now-illegal ones.
