Rule 108.4 · Cards

A card doesn’t have a controller unless that card represents a permanent or spell; in those cases, its controller is determined by the rules for permanents or spells. See rules 110.2 and 112.2.

Subrules

If anything asks for the controller of a card that doesn’t have one (because it’s not a permanent or spell), use its owner instead.
