I read it all except for the character specific part, it's very good, I agree with alot of stuff you say that is usually forgotten, like throwing the tomes and levin sword once their done, though I think you should add that catching the used items should not be made a priority, you should catch them only if it's safe, also usually if I land the last archfire and I can easily follow up with a levin-sword aerial I'd rather leave the book than waste the occasion, although this is debatable and heavily depends on the situation.
I don't completely agree with running away once you're out of wind tome or multiple equipment, yes, it's usually the safest option though it is really obvious, the way you can run away are either rolling behind your opponent if you're at the edge or jumping over him, and neither is usually safe, a predicted roll can result in being knocked out of the stage without recovery options and being on top of the opponent is a position with no options at all without elwind.
I'd say in that situation it can be better to stall your opponent, be defensive but don't run, if you miss only wind you can easily keep the opponent at bay with your standart tools(and wind has the fastest recovery time anyway),
Regarding the multiple-tools-missing situation, you should probably try to never let it happen, I know it happens, it happens to me too, but the equipment management is a core part of Robin and we should all make it a goal to master it.
I'd add to "Always charge thunder" a second rule in the form of "Always cast thunder", having a thoron sitting there if you don't plan to use it for the next 2 minutes is a waste of other options, I'm not saying you should waste it at the first chance, I'm just saying that while you have a thoron you can't use any of the other 3 levels of thunder that may come more handy in a specific moment.
Judge the situation and act accordingly, charging to the last level is not always the best thing to do.
Now regarding Nosferatu, I think it might be easy to land while the opponent is trapped into archfire, it would work kinda like this:
Archfire, dash, short hop, nosferatu. I don't think it's totally reliable but it worked quite a bit of times for me, I might test it out later to figure out proper timing and things like that.
Just to leave some personal experience, yesterday I fought a good villager that after pocketing elthunder one time and archthunder two times in the course of 3 matches, always tried to predict my archthunder to pocket it, I took advantage of it by charging all the way to thoron and storing it since he would let me do it for free and thoron was quite effective. Key to victory for Robin is capitalizing on the enemy's mistakes!
Also if I didn't miss it I think you forgot to say the thunder tome recharge time.
By the way, hello everyone! I'm new here, I just got the game for wiiu and main Robin, hope we'll be able to figure out the way to victory together!
As I said I just got the game so if a said anything stupid fell free to correct me, I have a lot to learn.
Also I'm sorry for any spell error I may have made, english is not my native language, feel free to correct those too if you feel like it.
