A General was about to lose in a battle

Suddenly a deity came to help and turned the tide to his favor. The general was quite grateful, kneeled down and asked, "What is my savior's great name?" The deity said, "I'm the god of practice target."
The general baffled, asked again, "What merit do I possess, that the God of practice target came to my rescue?" The deity explained, "Well, I came to thank you that you never hurt me on the practice field."
