I got this on Train Compartment Scenario using Sir Knight against Grisha.
You want to be against Grisha as his main weakness are comments abouts his Country/Origin making the Phrase you need come up more commonly.
You can either do this with two controllers or go against the CPU as I did.
As soon as you get 'Your Country' keep using the (...) until you find the ending part of the Phrase.
Note that sometimes the (...) won't pop up.
This clip shows me doing it, ignore how poor Grisha is at trying to roast me
