I would have liked to see this concept as more of a like, dynamic tower defense as it were? Determining optimal enemy placements to prevent a hero from progressing, stealing their loot to upgrade your stuff. As it is it doesn't feel like you're much collaborating with anything as much as it feels like you're goldfishing a magic deck and I got the most enjoyment out of it just spamming bats and being destroyed, it was kinda a shame to see the idea was sort of the opposite, it doesn't feel good to be bad on purpose.
