lots of good test teams already posted, so i'd refrain from that.
here's my odi team :
openers :
sachin tendulkar [14146 runs @ 44.20 + 142 wks @ 43.61]
adam gilchrist (wk) [8025 rns @ 36.14 + 339 cts and 42 st]
middle-order :
ricky ponting [9020 rns @ 42.34]
viv richards [6721 rns @ 47.00 + 118 wks @ 35.83]
michael bevan [6912 rns @ 53.58]
all-rounders : [they often make the difference in odi matches]
imran khan (c) [3709 rns @ 33.41 + 182 wks @ 26.62 ]
kapil dev [3783 rns @ 23.79 + 253 wks @ 27.45]
bowlers :
wasim akram [3717 rns @ 16.51 + 502 wks @ 23.52]
shane warne [ 293 wks @ 25.73]
allan donald [ 272 wks @ 21.78]
glenn mcgrath [ 331 wks @ 22.43]
12th man :
who else, jonty rhodes. [donald , after finishing his spell could conveniently feign a back injury gettin jonty in the game

]
[mind u, the super sub rule is about to be scrapped soon; so we will be back to seeing the 12th man carrying drinks and doing the low-end job

of only fielding;
however ; a gr8 super-sub could have been :
sanath jayasuriya [ 10625 runs @ 31.9 + 273 wks @ 36.82 ]
the bowling on this line-up makes me salivate [we indians are a bit short in that dept. , remember ? ] :
We can have Mcgrath and Wasim opening the attack. Mcgrath will do his stuff obviously; if Wasim cannot swing the new ball give it to Kapil / Imran. Atleast 1 of them will surely click.
When the batsmen think they have somehow survived the opening burst( with the score reading 50/2 or 64/3 after 15 overs ) ; bring on Donald.
If nothing, his sheer pace will scare the hell out of those poor souls at the crease.
From the other end bring on Warne. Just imagine the batsmen having to handle Warnie's wrong - uns , zooters and flippers from one end and fending off Donald's thunderbolts at the other.
If the batsmen miraculously surive till the slog overs , bring on the reverse - swinging duo of Wasim and Imran. A few Wasim yorkers should suffice. If need be, finish the tail off with Donald and Mcgrath.
WOOOOOO !!!
