My take is to abuse it as much as possible with Voltaic Key effect. It seems logical then to use it alongside Grim Monolith and Mox Opal. If I'm going to use black tutors alongside Voltaic Key, then it should be obvious to play Time Vault. The rest of the list just is kind of obvious, drawing heavy inspiration from the 2nd place EW Japan list. (An interesting deck that I've enjoyed playing and managed to go 9-1 with in league) https://www.eternalcentral.com/asia-vintage-championship-2019-coverage-decklists-and-results/
