On this land, I'd like to give my opinion on who will win the Mirran-Phyrexian war:
Mirran.
There are many reasons why either would win (I wrote a list on the Mirrodin Besiged Plains, one of them) but I like the Mirrans. Rate my comment on whether you think which will win. 5 stars for mirran, 0.5 for phyrexian.

...I'm gonna feel really stupid if they lose.
