Thanks for playing! It sounds like you fell victim to the RNG, which is something I need to find a way to combat. If 2-3 knights spawn in a chokepoint it's often a run ender. The only real way around it is to focus on weenie-spam instead of big boys, but it's often too late to correct. One thing I'd like to add in a follow-up is spells that can be cast during the execution phase, where you can disable a tower or freeze a minion, which should give the player a way to get past bad situations like that.
