Had my first experience against a Jacques, I am #1 power in my kingdom against the #1 of another kingdom with very similar power, dueling in my own territory. So I just go full swing on him with silver/golds along with heroes. Dude deploys only bronzes and heroes, one of them being Jacques. I do defeat him but get over 12 hours of injury time. Jacques did more damage in that battle than my whole army combined.
Asking this out of curiosity but what's your power level? i mean you didnt manage to counter a jacques covered by a bronze army?
