Miss Fortune Double Up/Stormrazor Interaction
I recorded this myself because I write all the time how Double Up (Q) procs Stormrazor just to get downvoted or told I don't know what I'm talking about or that her Q never crits, or that Stormrazor doesn't apply because it's not an on hit effect or that her Q doesn't apply on hit effects, or some other statement that clearly lacks any knowledge of the champion. (In their defense the Stormrazor tooltip does specifically say your next "auto attack" but since it's an on hit effect we know what that means for MF.)
While it is true that Stormrazor does not proc on the first part of the Q (It never ever does, and I have tested this), it will ALWAYS proc on the second part regardless if the first target was killed, and since the proc is a critical strike it will apply the bonus % damage every time you use Q with the Stormrazor proc (although the bonus is reduced for this interaction). Zeal items however can proc critical strikes on the first part or the second part, or both, or neither depending on your critical strike percentage. Your critical strike percentage also applies to Bullet Time, but Stormrazor does not because Bullet Time does not apply on hit effects.
(For further proof you can watch my move speed change in the video when Stormrazor procs.)
I thought I would share this because I don't think a lot of people actually understand or realize how strong that interaction is (or that it even exists) and Stormrazor first item actually out damages Duskblade as a first item because of this (and the fact it has more AD which she scales VERY well with). Duskblade second item (the lethality is nice, but being able to run around without being seen is better) into an armor pen item (trust me it hurts) or Black Cleaver (I forgo the Ghostblade because I just build Swifties and press W).
Hope this helps any aspiring MF players to try something a little different instead of blindly following some Pro Guide.
I also run Dark Harvest / Taste of Blood / Eyeball Collection / Ravenous Hunter / Absolute Focus / Gathering Storm (as of patch 8.18)
I'm not saying this is bad or good, just the facts of the ability and item interaction~

EDIT: I wouldn't be surprised if this is a bug and it's actually supposed to proc on the first part only but then that may make it too easy to kill the first target and get the bonus damage anyway. Man what an item Stormrazor is... breaking the game in so many ways. Get that freelo while you can!
Double up has always interacted in this way with crit modifications. A physical spell that applies on hit effects and has a crit trigger tends to qualify for most auto attack modifications.
Q works the same way. Pirates/ Pirate Hunters (o^_^)p
is still a pretty good first item
