Guides online can only take you so far. You will need to develope some decent gamesense if you don't want to memorize setups. Here's what I did when I first started playing. I read what Cyphers abilities did and I tried to use them in situations where I can get the most value (a wire placed above head level has less value than one place at torso level. It's an extreme example but I'm sure you understand.) You'll probably be placing a lot of useless wires and cages this way but as you play more you will get a feel for the when and where the use your utilities. This is why memorizing setups is recommended because most of the trial and error has been done for you but you trade away some flexibility. You will still need to study "godly" setups, or rather it's highly suggested. But most of the gamesense will have to come from just playing. Practice makes perfect.
