This is the nineteenth instalment of the Fortnightly Topic Challenge described here, with topics suggested and voted on here. This fortnight's topic is "Unconventional Tag Fusion" (suggested by Alconja), and will span from the 31st of October to the 13th of November. During this period, we will compile the list of questions that use two or more tags not normally seen together (more detail below) and post it as an answer to this question.

Note: This is a little different from the usual single tag challenges. Your goal is to use two tags which would not normally be seen together on a single puzzle. It's up to individual users to decide if their chosen tags are "unconventional" enough, however, the intent of the challenge is that the two tags should seem like an unlikely pairing to a casual reader.

In other words, whilst you may like to draw inspiration from tags which are rarely paired, having few existing tagged puzzles isn't necessarily in the spirit of the challenge.

For example, a pairing of and isn't really going to surprise anyone so shouldn't be considered "unconventional", even though there are currently no puzzles tagged that way. Better examples might include (but are certainly not limited to):

Ideally, puzzles should involve the two tags being genuinely merged into a single challenge, rather than just having a two step process of, applying tag A then tag B.

In the meantime, please go and propose and vote on future challenges!

Everyone have fun, and happy puzzling!
