I'm really enjoying them. Some mechanics we've seen before but either presented in a different way or with a different tell to keep things interesting. Though some that were exact were fun. I laughed a bit in M3 to think "Ohai Emerald Weapon, good to see you again". They are spicy enough to keep things exciting mixing familiar mechanics with a more fast-paced style without being overly punishing so that a struggling party can still make it through.
