Taking on the Martians again, are we?
1. David Warner
Is in the form of his life currently, and has the ability to make big scores very quickly. Can't say I'm a huge fan of him or his style of batting, but he is talented and his recent results speak for themselves. Can take the game away from you in a matter of minutes.
2. Chris Gayle
Does the same thing as Warner - if he comes off, you get a ton of runs in no time. He can also turn the course of a match within a couple of overs, and his bowling adds value to the side.
3. Mahela Jayawardene
Has proven himself time and again as a player who can adapt to anything. He is capable of anything, can bat anywhere in the order and has a wealth of experience from 500+ international matches during his career.
4. Suresh Raina
With the short ball having less of an impact in T20, and Raina's boundary-clearing ability, he is seen as one of the best batsmen in the world at this format. When he's on-song, anything can happen and the game can turn in an instant. Plus his off spin could be handy, with only 4 specialist bowlers in the side.
5. AB de Villiers
Top class batsman that can score quickly without taking any risks. Plays proper cricket shots beautifully and effectively, can hit out when needed and is a fantastic fielder. Would also take the gloves if it weren't for the next man.
6. Jos Buttler (wk)
Left field selection of the side, based more on intuition and prodigious talent than pure statistics. Buttler has a tendency to play the big innings when it matters and, with time on his side, should develop into a brilliant T20 player. His List A stats are ridiculous too. Plus the Martians wouldn't likely know who he is.
7. Michael Hussey
Mussey is the ultimate player to have on your side. He can read a game perfectly - knowing when to consolidate and when to attack, how to bat with the lower order, rotate strike, clear the boundary and do almost anything in the field. His experience and knowledge of his own game would be vital in the side.
8. Shahid Afridi
Was originally going to leave Afridi out in favour of a third seamer (or someone less insane), but instead decided that he could play an important role in the side. He can be counted on to add a few runs to the total in very little time, and then take wickets and restrict runs simultaneously. Only question is to whether he could slot in to the team without ego getting in the way.
9. Daniel Vettori (c)
Vettori has a crazy-low T20I economy rate (under 6 IIRC) and is a fantastic limited overs bowler in general. Experienced, capable and able to restrict even the biggest Martian hitters.
10. Lasith Malinga
As if a Martian could understand his action. Jamming yorkers onto middle and leg at pace, he's the first name on the team sheet.
11. Umar Gul
5/6. Late conventional swing. Reverse in 9 overs. Fantastic death bowling. Need I say more?
