MTG Salvation

Yeah I know it's unfun to play against this deck more a proof of concept. Like black control on steroids. I've been thinking like esper artifact recursion to get mindslaver back a bunch while copying instants with the blue to get multiple copies of like worst fears, and other socreceries, like cruel entertainment.

I've been playing edh for about a year and I've built some fun wacky decks that eventually become something I'm proud of, and semi-competetive but I've been brewing the idea of a turn stealing deck. I want to control other people's permanents and their turns also possibly with a sub-theme of curses to maximize other player targeting. Any suggestions?
