What do you guys make of my Scrap deamons?

I play Chaos Knights and built some decaying rust machines to fit my army better, I just thought what do true Nurgle people think, and would you have a problem if you opponent brought these to the table? I got 9 Scraplings, 2 Rust of Nurgles, and 1 Scrapy-guts (Last two are built but yet to be painted)
