• The most general thing I can say is about the usage of notes. You have a huge amount of different build options in your cheat sheet, but that also means you have to make it clear for the reader when to take option X. You can either use the titles or notes for this. For example, right now for certain runes you have indications of "safe" and "aggressive" options, but when am I supposed to go with the "mana restore" or the "spellbook" pages?
  
  
• Sort of related to the point above: some of the notes you do have seem rather irrelevant. For boots choices for example; "Choose depending on situation" still doesn't tell the reader on when to go for a certain option. You can explain this in your notes with a simple but effective explanation. For example: "Mobility boots as the standard choice, Merc's against heavy CC comps..."
  
  
• For the support role you have 2 different item tabs, one with all the options and a full build and then another tab with even more full builds. It seems kinda odd to me to not just put the first full build in the second tab together with the other full builds.
  
  
• In your midlane and toplane "tenacity" rune pages, you do not even include anything that grants tenacity. Maybe you meant to put Legend: Tenacity instead of Legend: Alacrity?
  
  
• You have a botlane rune page titled "damage", but it's a page with Fleet Footwork, which is like the safest somewhat viable keystone on Pyke, not adding any extra damage instead of Electrocute, Hail of Blades... I do not really see the logic behind the title.
  
  
• On support Pyke you take ability haste and a defensive stat as your first 2 rune shards. 2x adaptive force has a much higher pickrate and seems like the logical choice to me. Not saying your setup is wrong, but it might be worth explaining your thoughts behind it.
  
  
• In one of your full builds you put Silvermere Dawn, but it's not listed as a situational item (at least not in your support build).
  
  
• In your midlane build, Sanguine Blade seems to be missing. Same situation as above.
  
  
• In your list of viable Ornn masterwork item upgrades, you put Syzygy and Sandshrike's Claw, but in the rest of your cheat sheet Eclipse and Prowler's Claw are nowhere to be found.
  
  
• In some of your builds you have a lot of items marked as "core items". But you'll never be able to buy all of those in a single game, so maybe split it up and create blocks with different cores people can run.

• Maybe it would be a good idea to merge these 2 chapters, since both are really short and "About Pyke" is basically an introduction to the champion.
  
  
• I think it would also make sense to move the showcase of your versatility award to the introduction. So it can serve as a form of credibility, to show of your guide is a good one!

• I would personally opt to remove this chapter, it's not informative and doesn't really add any value. The only reason I could see to validate a skin chapter is when some skins have better/cleaner animations or effects that give you an advantage gameplay-wise.

• Maybe it might be worth noting that Pyke can generate quite a bit of extra gold through Death from Below and 'your cut'. But this is only a small suggestion.

• Since you got some kind of mini ToC at the top here, I suggest also adding links to jump to the different rune trees.
  
  
• You got many different options here, which is okay, but it also makes it harder to maintain clarity. I don't think it's useful to go over options that are terrible on Pyke and should never be used. It's already obvious that certain runes like Guardian or Lethal Tempo should never ever be used on Pyke. Instead, I'd just take the runes that are at least situationally viable and explain why and when to take them. So in general I would explain less runes, but go more in-depth with those left.
  
  
• The descriptions of Predator and Sudden Impact still contain outdated numbers.
  
  
• Ingenious Hunter has been changed to grant Ability Haste instead of CDR now.
  
  
• In my opinion, the description of Ravenous Hunter is somewhat confusing. It kinda sounds more like Triumph to me. It would be clearer if you just state it grants omnivamp.
  
  
• The description of Triumph itself is also confusing to me. It doesn't keep you alive in a 1v1 situation, it rather helps winning a close 2v2 if you manage to get a takedown.
  
  
• About Lethal Tempo: "Gain a large amount after damaging an enemy." A large amount of what? -> attack speed.
  
  
• You only tell explain that Fleet Footwork makes your attack energized, not what that effect actually does. The healing and bonus movement speed is crucial to its functioning imo.
  
  
• It might be worth noting that Minion Dematerializer also increases your damage against minions after using it. For a champion like Pyke who has a hard time farming solo I can imagine that's a crucial detail.
  
  
• Transcendence is outdated after the change from CDR to Ability Haste.

• Clean and tidy chapter, but maybe a little short. I'm pretty sure there is a lot more to say about how to use Pyke's abilities to their full potential. Maybe also add why you max Q>E>W for example.
  
  
• Just a detail, but it might be useful to specify that Phantom Undertow does only damage enemy champions.

• Seems like there is a small coding error here. The content is slightly to the left instead of centered like it should be if I'm not mistaken.
  
  
• I would add something about the grievous wounds aspect of Ignite. In the botlane it's super important to be able to reduce the healing of certain enchanter supports like Soraka.
  
  
• You put Heal and Smite in your cheat sheet, but those are missing here.

• I do not recommend talking about old items that have been removed, since not everyone does remember them or has played long enough to have ever known them. For example Steel Shoulderguards; I recommend talking about what it actually does, not about what it used to do or what Relic Shield used to do. (Something else specifically about Steel Shoulderguards; I get what you mean by linking Minion Dematerializer with it, but not everyone might understand.)
  
  
• You state that Ravenous Hydra is the best item on Pyke, but I don't think it's something you build in every game. (And it's absent in most of your builds as well.) It's probably the best item for solo-laning and jungling, but most players play Pyke support, so it's not a general rule.
  
  
• This chapter is rather short, I recommend adding the other items you put in your cheat sheet. Most items can definitely benefit from some extra explanation.
  
  
• I feel like the titles above each item are a little too big. Maybe try to reduce their size a little to keep it more in line with the rest of the guide. (Just saw you already planned on changing the look of this chapter, good!)

• Gameplay sections are often "extra" stuff that isn't 100% necessary for the reader to learn the champion, but still I feel like you could talk a lot more about some topics here, like warding. You got an image to show warding spots, but you could tell a lot more about what locations to ward at which point in the game (for example botlane tribush during laning phase), where to place Control Wards...
  
  
• I think there is some crucial info missing about roaming. You mention whether to roam or not, but I think it's also worth noting WHEN to roam. Like roaming right after recalling as a support for example. Or when you are playing midlane, always pushing the wave before roaming so you lose as little gold and exp as possible.
  
  
• You tell readers they should roam when the enemy team has Nasus/ Veigar/ Kassadin. Why? Because they are weak early but will outscale everyone else? Whatever the reason is, I think it's good to explain why.
  
  
• Since Phantom Undertow doesn't damage monsters anymore, starting with Bone Skewer as a jungler is probably necessary.
  
  
• Overall there's just a lot more info you can add here. One of the most potentially useful subjects is probably jungle pathing. As Pyke you can't just full clear, you need to path smart, focus on single target camps like gromp, blue buff and red buff and then gank as soon as possible.

• In my personal opinion, patch notes like these are rather irrelevant to a guide. Readers who are checking out your guide in order to learn how to play Pyke right now do not get any value out of the changes from several seasons ago. If you really want to keep this chapter, I recommend putting it in a spoiler like the update section.

• This is a multi-role guide, which isn't easy to write. Trust me, I know the struggle. Crucial to make it work are super clear explanations. I think that's the main point of improvement in your guide. Try to reduce the amount of options when they aren't relevant anyway and focus on explaining what is useful. This is the most important information that you should give while explaining items/runes/spells...:
  
  
  • Why would you ever take it on Pyke? Why does it work? For example, Youmuu's Ghostblade is good because it grants you a lot of damage while also increasing your ability to roam.
  • When should you buy it? In what specific situations? For example, Chempunk Chainsword is really useful against champions with a lot of healing like Vladimir or healing enchanters like Soraka.
  • Is there a difference between roles? Are there roles where this option is viable, but is it useless in other roles perhaps? For example, Tiamat isn't worth buying as a support, but it's necessary if you are a solo-laner or jungler.
  
  
• I already mentioned before but you tend to talk a lot about features that have either been removed or have been changed. This won't really be helpful for many readers, so I suggest toning it down and talking more about the present stuff. Take Duskblade of Draktharr as another example: "The ability of seeing wards has been removed." isn't really relevant info for those playing with the item in season 11. Instead, you could say something about the extra burst damage and the invisibility on takedown.
  
  
• You often seem to write down explicit numbers from stats, especially in your rune section. Nothing wrong with that, I often do that too, but it'll be harder to keep everything updated since Riot often makes small number changes and it's easy to miss them. You could also explain runes without diving into number details, which will save you work. (And I won't have to annoy you as much because of outdated content!)

• Overall, I think the presentation is solid. Clean and tidy formatting is even more important for a multi-role guide because of the huge amounts of information, but you seem to pull it off fairly well.
  
  
• I definitely like the style of the visuals, there's some unique stuff and it fits perfectly. However, I feel like your guide might gain a little extra benefit from some more consistency in the theme. Right now each chapter seems to have a slightly different visual style. For example, in the pros & cons section there are white lines, in the ToC you work with red/yellowish accents, in the ability section you got cyan lines and accents and in the spells and item sections you use yellow accents. It might be a good idea to choose a smaller color scheme and stick to it, matching your banners. For my guides for example, I usually pick no more than 2 or 3 colors.
  
  
• Please keep the humor in this guide! I like it a lot.

Overall I think this guide has lots of potential, but it needs a little more work to reach another level. It's really ambitious and bold to create a guide like this while most veteran authors wouldn't even dare to try it, and you pull it off fairly well, so credits to you. :) You got the versatility award, that means something, but in order to succeed even more with a multi-role guide you should try to keep the organization a little cleaner. Cut out the irrelevant content and replace it with information that is really important to readers. Obviously whatever you do with this review is completely up to you, but if you decide to make some changes please do not remove the humor and visual style you put into it. Those are definitely highlight to me. ;)

So this marks the end of my review. If you manage to improve some of the things I pointed out, I truly believe you can create something even greater out of this guide!
