Right. So if you put this card on a Troublemaker, you can move it to a Problem with another Troublemaker, force that card to be dismissed, then move your Troublemaker away from the Problem. The really nice thing is that this trick works even if the other Troublemaker is Epic: if there’s a uniqueness violation involving multiple players’ cards, the player who most recently had priority (in this case, the player who activated that Main Phase ability) gets to decide which cards are dismissed.
 
It’s not something you’d want to do frequently–there are cheaper methods of Troublemaker removal that can be built into your deck–but it could be useful in a pinch.

The “Epic” trait makes Troublemaker prevent BOTH players from confronting a Problem, but both players can challenge them for points.
 
Epic Troublemakers also prevent other Troublemakers from uncovering, and if there is ever a face-up Epic Troublemaker at the same Problem as any other Troublemaker(s), there is a uniqueness violation and the non-epic one(s) will get dismissed first until there is only one Epic Troublemaker left at the Problem.

@Background Human  
Is that what epic does?

@Background Human  
By the wording: It seems you can only play it on your own trouble maker, and then move that one. So I don’t think you can move others.  
Unless there’s some rule thing/card I don’t know about~

The nice thing here is that you can use that main phase ability to clear out other Troublemakers from Problems. The Great and Powerful Trixie won’t be upstaged by anypony.

So Trixie’s mistrust of wheels was a paranoid delusion caused by the Amulet? Neat.
