The Original argument to put Magnet Release as Wind and Earth was...

"Rasa has the Wind, Water and Earth Release. Wind and water creates ice, water and earth creates wood, so the only possible combination left for Magnet Release is Wind and Earth Release."

Now Shinki has come along and shown neither and only has shown Lightning. Thus, this counters that since they're both Magnet users and Rasa has those three natures and Shiki only has Lightning. Although it's anime only, the anime is canon since it's supervised by the writer of Boruto and occasionally Kishimoto himself.
