I did end up putting Arrangements for War in the final list:
Live 34 doesn’t necessarily fit as part of the direct arc, but I would still recommend it. It’s really good. Magic Mousetrap is okay, if a bit weird and confusing. I’d say it’s more set up for the Black/White arc that comes after A Death in the Family than for Death proper.
Oh, I looooove The Magic Mousetrap. I think the characters are so fun and the plot is so creative. It is definitely weird and strange but I like that about it!
Magic Mousetrap is my favorite Toymaker story
What’s everyone’s favourite science-y episode? I have my Science exam tomorrow and I need to do some revision 
Does Bidmead Who count as science-y? 
Good luck with your Science exam tomorrow!!
Well everyone knows Kill the Moon is very scientifically correct
The Mind Robber.
What should I listen to next?
I don’t like to sound annoying, but here’s another poll 
After I finish ‘Doctor Who and the Auton Invasion’, what should I read next?
I’ve read Cave-Monsters, and I really recommend it.
Great read.
I am terminally indecisive and the wheel keeps failing me
You lot have excellent judgement. Went in expecting a mediocre episode, ended up with one of my new favs.
It’s Douglas Adams, so of course it’s a good one
Now I’ve finished Vampire Science, which book should I do next? (although technically I’m part way though all of these, so its more like what should I finish…)
I will always advocate for Leisure Hive, god bless the Foamasi
Hail the Foamasi!
I love love love the Scarlet Empress 
Currently bored. Planning on rewatching something.
It’s settled then.
The God Complex!
Which Rani episode should I watch?
