something’s missing

Why?
the full sentence is "And just think – the best magic is, that they are for real! "

It only makes sense if you remove the comma - that was my doubt. Maybe they left off a word.

Not sure who is the author, but website owners are "a small team with big ambitions. We are: Maj-Britt Skrubel Permien – former IT entrepreneur and Product manager, Michael – former IT Service manager."

Yeah, we don’t use commas with THAT like you do in Russian or like in German, for instance.

Actually, there are a lot of non-native moments in that article.

Thanks a lot for comments!!!

No problem)))
