Asuma's wind tech is dust cloud, its a very narrow laser like attack only with heavy spiraling wind in it. If used in the mist, more than likely it would just make a narrow hole in the mist. It isnt like Wind Slythe Jutsu, it doesnt cover all ranges, Dust Cloud is more focused.if asuma can use wind style to blow away the mist i vote either darui or asuma
style
asuma or darui high diff ( if the mist can be blown away by wind)
