i was using card clasher to bot some high hp bosses today and left it and came back only to see that i was on the same boss and constantly dying.
after some observation it turns out that the bot will only use either 'deal' or 'tap'. once it uses the skill, it will try to use the next skill IMMEDIATELY, so the skill won't even work because all the skills refresh once you use any skill
that was a bit complicated let me give you an example
card clasher is fighting boss
card clasher uses deal
card clasher then tries to use tap the very next millisecond
card clasher fails to use tap
card clasher dies
