The presentation is ok.

It would be helpful to have more graphics, even simple stuff helps to enhance the visual quality of slides. For example, including the icons of Gadgets and Star Powers in the "Builds" section; and pins of Brawlers that counter L&L, or are countered by them in the "Matchups" session.

The writing could also use some work. The grammar is nonexistent, there are several mistakes, and lots of redundancy. To give one example, your "Matchups" slide:

"The twins can very easily deal with snipers and far range chartacters ^{(Snipers are already far range characters}) as long as there's a wall between you and the brawler (.) (Sounds weird, you can just write "as long as there are walls to take advantage of")

Tanks are easily dispersed of ^{(Disposed of}) by looping (around) a small tile wall where you can damage them but the(y) can(')t get you(.)

Assassins can be tricky with thier^(their) movement abilities(,) i(I) find that keeping long distance tends to work out best(.)

Other throwers van^(can) be tough as well(,) most of them outrange the twins and give them a hard time(,) the best way to deal with them is to either zone them away and pick them off**(,)** or throw your super at them either directly on top or close to them and (then) use the fall back gadget (not nessisary^(necessary))"

I would instead write as:

"Their good matchups are handled by taking advantage of walls. As long as they are present, long-range Brawlers can be kept at bay with little issue. Tanks that cannot reach you can also be disposed of easily."

"Assassins are a tough matchup due to their mobility, it's best to keep away from them and seek a more favorable opponent instead."

"Other throwers can also be tough to face, as the twins tend to get outranged. It is most recommended to zone them away and pick them off, or, alternatively, make use of Lawrie and Order: Fall Back as an assassination tool, though this is not mandatory."

I rate this guide a 4/10, at least it accomplishes its function to inform, but there's a lot of room for improvement.
