A couple years ago, I wrote some js to sort a 5 letter word file. The value for a word was based on letter frequency in each letter location. Then I took the words that didn't have repeating letters. The I choose a word at the top that I liked and grep'd for some other words to use for the 2nd and 3rd try. In 3 tries, you have used over half the alphabet and all vowels. This usually lets me get the word by the 4th try. Here are some word sets you can start with.
- pares, moity, bundh|bunch - pares, monty, build|guild - pares, doily, bunch|munch
- pores, banty, guild|mucid - pores, canty, build|guild - pores, manty, build|guild
- bares, ponty, guild|mucid - bares, moity, punch|dunch - bares, monty, guild|child
- cares, ponty, build|guild - cares, moity, bundh|gulph - cares, monty, build|guild
