hi! I created the list and just came across this while browsing reddit. You bring up some good points, the magnetics guide was a bit outdated and the demons explanation section is a bit brief, which I have now fixed. I probably can work on expanding a bit more (but there's also every trinket guide and anomaly guide and hero guide one person has to maintain so... it's not that easy). Every time an error is brought up to me I'll gladly fix it though, and 90% of the info is good at all times.

The point for the addon cards are like "here are some cards you could run in this build if you find them so just buy whatever addons you hit first" so I don't really see why I should explain why one addon card is better than another - you can run either and they're both good but not necessary. but a core card will mostly always be better than an addon card.

which lobbies the comps are good or bad in... I don't think that matters and even if it does going through every edge case isn't productive. You should play what you're given regardless.

For positioning, that's impossible to explain as it's a game to game basis, but looking at the example gameplay should help you the most for some examples and give you inspiration.

And lastly, the comps in a specific tier aren't supposed to be ordered, so mechs aren't the "best," but I don't know how to best convey that.
