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?
Of the ways to control other people during their turns, I think they're all either black or colorless, so you'd probably want black. That said, mindslaver is probably the easiest to reuse.
I can't think of very many effects that are less fun than having someone else control my turn, though, and I don't think that's an uncommon opinion. If you're looking for "fun wacky decks", I'd look elsewhere.
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.
Have you considered Jeleva, Nephalia's Scourge as a commander? Most recent decks feature her as a competitive card-advantage option, but you can build around using her ability and big fun spells.
I have a fairly outdated deck here that has a basic structure, which was originally themed similar to what you're interested in. Cards like sadistic sacrament can be cast from under Jeleva and you can actually pay the kicker for the additional effect. I used to run cards like lord of the void since the deck had a pile of haste enablers for Jeleva, and remember a few fun games where I was able to resolve a rite of replication on the lord, which really tends to perturb opponents.
An even more enjoyable alternate win-con is to simply sacrifice & recast jeleva multiple times using cards like ashnod's altar. Her exile effect grows with every resolution, and if you've cast + resolved her 7 times in the same game then she would have exiled a total of 70 cards from all players. This should be enough to mill everyone out by that stage of the game, so you can just pass turn and let everyone draw-death.
A word of warning tho - people tend to hate Jeleva due to how the games always play out. People hate exile-piling for you, and once you end up having to remind them it's all down-hill from there.
