By saying cheat sheet I refered to the champion build(s) in the guide editor thus you just need to edit this part:

Hi emoriam! Thank you for your constructive comment! Yes I would have happen to have a question. How do I change Cheat Sheet? So to answer your questions.
1. You can always trade 1 Enchanted Armor for Unyielding, It doesn't make much difference because you will be taking Cloth/Null Magic on start. I don't go 21/9/0 because of the simple reason I think there are masteries that can really benefit Rumble more than standard. For example killing minion for health is great way of sustain early game which Rumble doesn't have. Or if you picked defensive way it is compensation for Runes that are (in my opinion) best for Rumble.
2. Yes, I will be adding 2 new blocks about Tricks & Tips, certain matchups and few actions with Equalizer.
3. No I don't buy Lich Bane often, but certainly is a strong item on Rumble despite mana wasted, cause his abilites are spammy and their CD matches nicely with Lich Banes CD, it can be amazing.

Hey there!

In your cheat sheet (the summary right at the beginning of the page) showing 'Start item options' might be more helpful than showing early game item pieces. You can also include an upgraded Trinket, Elixirs and boot enchantments to the builds.

Concerning masteries I'm wondering why you don't select Block and Unyielding instead of Enchanted Armor and overall don't aim for 21/09/00.

You display many matchups in the chart but you don't provide any additional information on them. Just add brief notes about what makes each specific matchup easy / difficult and how to be able to handle each lane opponent.

Do you really ever purchase items such as Lich Bane in any of your games? In fact, even if you're mileees ahead of you opponents I guess building other AP items is genuinely better.

I'd love to see a chapter on using The Equalizer in team fights / certain situations correctly by means of examples.

Feel free to ask any questions!
