Minato takes this. The only 2 counters that might work against him are Garra's sand and Mei's solid fog. However, given recent chapters, it would appear that Minato can make barriers with kunai that he isn't touching as well. Gara's sand doesn't work against marks because Minato can use space-time barrier to teleport it to an isolated kunai. He can do the same against solid fog by throwing a kunai near Mei. He did throw kunai's into the sea after all. Minato's KCM and FTG makes it impossible for an enchanced Ay to keep up to.
