The best way to get brilliant moves is to play more and more instead of trying to copy those brilliant opening moves from youtube.
If you keep playing more and more games, you will automatically have a higher chance of playing a brilliant move (only if you play seriously)
And playing a brilliant move is not all about chess, chess is an art, an emotion that only serious players can feel. It feels amazing when you involuntarily start thinking of chess even when you are not playing it.
