This is I think the strongest puzzle I've put together to date. If you want a hint towards the theme please check the blog post. As always, would love any feedback. Cheers and happy solving!
Hint 1: Every themed entry in this puzzle will be composed of the characters of two words from a common three word phrase
Hint 2: The missing letters/word from each phrase is IN, but the word “in” makes itself present in another way
