I know mech can be hard. But If we have a voteless phase, might as well use it. So here's a rundown of how we should be using this phase:
1. We should assume most dreams give a mildly useful invention to a random player. This is based on Miscummer Night's Dream I, where most dreams awarded 1-shot abilities (for example a 1-shot BP, 1-shot vig, etc.). Yes it can give these inventions to scum but assuming they resolve at the beginning of the night phase then if we mislim a townie the inventions have 75% chance to go to town and only 25% to go to scum (for N1, obviously. The percentages change on later days).
2. What utility does "Slide" give? Slide gives the following utility: Assuming there's collective agreement to collapse on someone who'd normally be hammered, it prevents quickhammers on claimed PR (probably not very useful D1 because scum are unlikely to quickhammer a claimed PR on Day 1 since that's a bad trade). I guess it adds 3 days to the deadline which means more discussion time, but IMO that's neutral or even NEGATIVE utility (explained in the bottom of the post becuase it's subjective and not objective).
Now, if you want to avoid Slide happening later and fucking things up, what should you do? Simple! Don't vote for it and the mods will REMOVE IT FROM THE POOL. Ideally we should aim for an invention or some sort of info drop or NK prevention if that exists.
Also, if we are not happy with the top pick, it's FINE because it gets revealed and we can always pick another option. That's what the dreamer is for.
Why is more days negative utility? Because longer deadlines make towns apathetic and give scum more elbow room to do their stuff (scum is being wagoned 2 days to deadline - plausibly gets hammered. Scum gets wagoned 5 days to deadline - scummates say "there's so much time, don't hammer yet!!!" and then a counterwagon forms or something because people get bored of the wagon).
