Double post.

Again, let's look at what persephone did not pick! Sometimes what a FS does not pick is as important as what they do pick.
Suffocation and Severe Injury are also not likely to have too terribly much in the way of overlapping methods, although it was easier eliminating poisonous methods. So as it stands, murder methods that would primarily suffocate should also be eliminated, I believe. I think early on, making obvious associations and eliminations is easier, and we want to do that now. As the cards go on, they're more likely to be more obscure and harder, so I think the first few cards are vitally important for making our first clear eliminations/deductions.
Pillow would fit Suffocation better than anything else. Plastic bag and Scarf would better fit Suffocation than anything else. Drowning is a direct method of suffocation. Towel is something that, like scarfs and plastic bags, is best suited to suffocation. I can't imagine persephone picking 'severe injury' for any of these things, especially considering that there are a lot of things that very readily take 'Severe Injury" as a more obvious association.
So that narrows it down quite a ways further for the Cause of Death. Revised strikeouts:
