For someone recent Natasha issues, I really loved Avengers Assemble #14. I thought it was a great showcase of her character, a wonderful issue devoted solely to her that punches me in the heart every time.
I know I don't have the most popular opinions regarding Nat in these parts, but I also personally really loved the Natasha of Secret Empire. Natasha who was heroic and a big part of the resistance team until it became clear to her that they were failing and she had to do things her way. And after that, her training the young heroes but also sacrificing herself so that they didn't go too far, didn't become like her. I just loved her in that event so much, plus Andrea Sorrentino's rendition of her was absolutely stunning! Forever in love with the splash page of her fighting Punisher. That's the Natasha I miss. I know dying and coming back as a clone changes a person and all, but she's been so cold since. I hope her new ongoing will deal with that and have her working past it and letting her friends in again.
