Great point. The idea was to have things you need (e.g. ritual) attached to things you don't want (e.g. bigger monsters), which then requires you to get more damage cards, etc.
But at the moment the pairings are just entirely random, so I imagine the combinations that happen to come up will make a big difference in how necessary particular card pairs feel. So there definitely needs to be more of a drive towards the player needing to pick the things that push them towards engaging with the more interesting mechanics.
Thanks for playing!
