So, full disclosure: I am strongly in favor of identical starting hands for tournament play, I used to play only with identical starting hands, and I sometimes wish that automatch had an identical starting hands option.
I don't buy the "different splits make more interesting strategies" argument. I agree that they often make *different* strategies, but I would guess that the ratio of games that I've played in and would describe as "less interesting because of different splits", versus "more interesting because of different splits"* has got to be something like 3:1 or worse. I freely admit that number is completely made up and that it is likely highly influenced by selective memory, or whatever the term is that describes my tendency to remember the time I lost to a level 1 because he opened Witch/Chapel. (Not that I'm still bitter about that or anything.)
I'm not sure I buy the "these aren't the rules" argument either, and for two reasons:
1. The rules do not specify that the winner must win a best-of-seven, and they don't specify that point counters are required, and they don't specify that an opponent may/may not reject the proposed set until he finds one he likes (which is not addressed in the rules post, not that I would expect anyone to do this...at least, not if he wants to be respected in the morning). Since the tournament rules do specify best-of-seven and random kingdoms, clearly we are already making *some* concession to mitigating the effects of luck.
2. Imagine that the rules DID specify that each player were to get identical starting hands. Would you argue, for the purposes of running a tournament and determining a champion, that it would be better or worse to determine starting hands randomly?
