Play devil's advocate is the standard verb phrase. In this pattern, play does not change to do, make, or perform. You can also act as a devil's advocate, but that is a different pattern.

What doesn't collocate
First, avoid perform devil's advocate, do devil's advocate, and make devil's advocate. Use play devil's advocate or rebuild the sentence with act as. Second, keep the possessive in devil's. "Play the devil advocate" is not the standard phrase. Finally, do not use the idiom to hide a personal attack. It names a contrary stance used to test an argument, not conflict with a person.

- opening a challenge to a plan the team already agrees on
