Archer has certainly been a revelation for England. Pretty casual/effortless approach to the wicket and then that quick arm swing action deceives batsmen in picking his line/length as ball seems to "rocket off" from the pitch and fast too - tends to bounce higher/lower than batsmen expect. Moreso, if pitch ain't up to standard as was the case during the 2nd test. Archer will certainly prove to be a handful for the Aussie's to withstand over the remainder of the test series.
