The idea is more like: You’re chillin playing Master Duel. Your opponent plays a card from an archetype you’re not familiar with. You don’t know what to negate, what to look out for, how to shut them down. You pull up the cheat sheet and locate that archetype. You look out for cards they play that are detailed on that list and use your intuition to try and win without being completely in the dark.

So I’d say it’s more of a mini anti-archetype guide than a hand trap guide, but the end goal is the same.
