Then you've done a good job on taking one small, obviously hyperbolic aspect of a larger point and completely ignoring the actual point.
Say you play the last World T20 ten times in different realities, you'd probably be lucky to see the same team win in more than 3 of them. Of course better teams are more likely to win, but you can't deny there's more luck involved than 50 over cricket or test cricket, and single pieces of luck have a higher chance of deciding a match. If you played the 2003 or 2007 ODI world cup ten times, I'd bet Australia would probably win 9 out of 10, same with the 2011 world cup, India would probably win 7-8 times out of 10. I don't think you could say that about any world T20.
obviously not all you need to win a world T20 is "a bit of luck". Don't take everything so literally.
Such as? Other than just "clicking", as you said, I can't think of much we really need to do as far as skills and tactics are concerned.
It is funny that Australia can be so dominant in World Cups, yet not play the big moments well in T20 world cups. It can't just be coincidence. Possibly I'd put it down to Australia not really caring about T20 up until the last one in Bangladesh where we seemed to be taking it seriously leading up to it, but then just played ****. But then we didn't win the ODI World Cup in Asia either so maybe it was largely a matter of conditions. But yeah we were pretty shocking in that last one.
