Here’s a randomly generated cipher of unknown type. Two of my ID tests put the correct type on top and two put it in second place. Hill-climber got a practical solution without a crib, and I put in a crib with some obvious corrections and the hill-climber got the exact solution. Converging key search solved it without a crib. I’ll add a Caesar-shifted crib.
