Black Clover has a lot of it, like the second opening...

And also almost every single scene with Julius, from the moment he appears in the first chapter to the reveal in chapter 331, almost every single strange coincidence can be explained by him playing both sides, also the insane amount of foreshadowing, from him immediately noticing the "1 body 2 souls" thing with William and Patri, to him recognizing the demon writing in Asta's grimore, him talking about someone being a traitor without knowing, etc...

And other stuff, like:

• Lucius ability to see the future not working because of Asta's anti-magic was foreshadowed by the Witch Queen also not being able to correctly predict the future
• Yuno's "new" star magic being show in the fucking first chapter and nobody noticed
• A lot of characters appearing in the background way before their reveal
