That's why this technique is good though.
Look at the 3 words I modified..
kryptonian, muggle and the last was '47 ronin'.
Alternate case, make some substitutions for letters with numbers/symbols, add in additional numbers/symbols, and you'jj have something that isn't trivial to bruteforce.
Once you know the core words you are using, you only have to memorize the substitutions you have made, which is much easier.
