I'm going to say "yes". The purpose of the trials is to find the best possible master of life, and refusing the help him only prevents us from seeing how good of a life master he is.
Remember, the deck doesn't have to be mono. Only 15 of the cards must be from life. This is important because neither you nor I will be stuck with life's advantages/disadvantages.
