Freelancer Market

{1}: Any target opponent creates a treasure token.
Any player may activate this ability. Then that
opponent may choose to activate one:
- Until end of turn, Freelancer Market's activator
gains control of a permanent you control.
- Until end of turn, you may cast a spell where
the word "you" refers to Freelancer Market's
activator.
- Activate mana abilities adding mana to
Freelancer Market's activator's mana pool instead.
