Can I move a Treasure Hunter on a Battlefield to Base, if I play a Tideturner in Base? Then switch locations, if there is an opponent's Vex on a Battlefield?

Question

Accepted Answer

Yes, you can partially successfully swap the locations of your units in this scenario.

### Ruling Breakdown
While **Vex, Apathetic** prevents **Tideturner** from moving for the entire turn, this does not negate the entire ability. According to **FAQ 7241**, if a swap ability's movement is partially restricted (in this case, **Tideturner** is restricted by **Vex**), the swap still partially resolves. The unit that is not restricted is still permitted to move.

Because the swap effect allows for partial resolution, **Treasure Hunter** will move from the battlefield to your base, even though **Tideturner** remains in your base due to the restriction applied by **Vex**.

### Sequence of Events
1. **Playing Tideturner:** You play **Tideturner**.
2. **Vex, Apathetic Trigger:** Because you played a unit, **Vex, Apathetic's** triggered ability goes on the chain.
3. **Vex Resolves:** **Tideturner** is [Stunned] and gains the restriction "They can't move this turn."
4. **Tideturner Trigger:** **Tideturner's** "When you play me" triggered ability goes on the chain. You choose **Treasure Hunter** (at a battlefield) as the target.
5. **Chain Resolution:**
    *   The ability attempts to resolve the swap.
    *   Due to the restriction applied by **Vex**, **Tideturner** cannot move.
    *   Per **FAQ 7241**, the swap partially resolves: **Treasure Hunter** moves to your base, and **Tideturner** remains in your base.

**Note:** Because **Treasure Hunter** moves, it will trigger its own ability ("When I move, play a Gold gear token exhausted").

Note: I could not fully verify this ruling against the retrieved rules.
