Luigi Main was definitely trolling me

Last night I played about 5 or 6 matches against a Luigi. In the first 2 matches it was like fighting a level 4 computer, but then afterwards he started playing much better where it got pretty close to where I almost lost. His GSP was like 3 or 4 million. Do y'all think he handed his controller to a friend or relative? It was like playing 2 different people
