good luck

1. Good fortune or a happy outcome, especially by chance. For example, It was sheer good luck that brought this offer my way , or, as Shakespeare put it in The Merry Wives of Windsor (3:5): “As good luck would have it, comes in one Mistress Page.” [Late 1400s]

2. Also, good luck to you . I wish you success. This term is used both straightforwardly, as in Good luck on your journey , and sarcastically, implying that what someone is undertaking is not likely to succeed, as in If you think you'll find that long-lost letter, good luck to you .
