The most destructive T20 openers ever

Last time I asked you guys who's the one bowler you would want in your all time T20 XI. Today I have come with something more interesting. Which pair out of these is the most destructive opening pair of all time? The only criteria of choosing is causing MAYHEM in the opening. My dream openers would be Gilchrist and Buttler for dismantling most of the best bowlers throughout their careers. Please let me know your pick, or if there is any other combo apart from these 5 and comment down what do you guys think.
