I'll look into it 🙂 What would be the optimal way these days to detect two creatures with a shared type on the battlefield without going through all the permutations in a loop (if there is a way)?

Filter out all 'all creature types' first

Good catch. If any of those exist then you could keep them separate until you build the map, then add them to each existing key afterwards?
