"Pull 'em out" > pull them out. No, it does not mean "take off the other teams". It means that their repertoire of songs and dances is great (many). The team is now going to try new songs and dances from their vast playlist never before performed in public, hence "pull 'em out". I don't know how else to explain it!
https://transcripts.fandom.com/wiki/Justice_League's_Next_To...We's got a deep playlist full of songs and dances, and we's gonna pull 'em out, yo! ***And I have the new song and dance I wish to perform . ALL: [HESITANTLY] Yeah We talked about this, remember, Star? Yes. You said I was the secret weapon and I would be used as the last resort. Uh, that's right, Star. As a last resort. [CLEARS THROAT] Because we don't want to unleash those moves on the world unless we have to.***
