Yes, Coco can survive in a "gentleman's meta;" where Hamburger-Time don't exist. Coco actually isn't that bad. She makes 21K columns well with Gemini and whatnot. She's decent.
But against the actual meta... hahahaha no. The cards you draw with her effect are going to be burnt up like paper by guarding Dragonic Overlord, The End and MLB turn after turn as the damage eventually will rack up. At least she doesn't require much set-up, but she's just not that great in this format.
She may get a new lease on life if the game switches from 13/12K dominance to 10/11K, but I doubt that's going to happen unless Bushiroad hits Dragonic Overlord, The End and MLB like they did in Japan.
