Sorry if these aren't very good, but I read the sticky and this is just a few ideas I have had. I am pretty sure they are original, for I searched for tags, and any feedback will be very much appreciated:
"Writer's Block"- This would be a partial-comedy SCP that would play off the term Writer's block. It would go along the lines of a giant marble or granite block in a smooth cube shape that, whenever touched by a person, that person will find themselves able to write anything for weeks. I don't know if it would be an actual good idea, but I kinda think it could be good.
"Oracle Bingo Spinner" - This is a rough idea, but it goes something like this: This SCP is an old bingo spinner, the ones where all the balls are in a sealed container that you can spin around with a crank until one of the balls falls out from the whole in the bottom of the container. Instead of dropping out white plastic balls with bingo numbers, it will drop out white plastic balls with a random event. This event can be good or bad, and will happen to whoever was cranking the bingo spinner when the ball fell out. It could have been recovered after a spinner in an old folk's home in [redacted] got trampled by an African Hippo, or something along those lines.
"Kharma" - A human SCP. Anyone who comes into physical contact with this SCP experiences an event of bad luck, ranging from something minor like spilling coffee on your clothes to being crushed by a falling piano. The severity is influenced by how long you are in physical contact with this SCP, and it was recovered after a string of bad events surrounding her (this SCP would be female). Then after the much more detailed explanation, there would be a test log with D class personal locking arms with this SCP for different amounts of time and seeing the results. Also noted no bad events can occur to the test subject until they let go of "Kharma"
those are just a few rough ideas I had, hopefully we can talk about them/improve them :)
