If 7 Wonders Duel strategy had a mantra, it would be “I don’t want this, but I’m going to take it anyways because you need it.” In a game where military is just a token that you slide, this is a surprisingly combative game. Every single choice you make, you second guess because what it might let your opponent do. So, instead of doing what you want, you take whatever card it is that helps your opponent the least.
