Ok, I got it.
Just did not know, that after eliminating someone, you get their spoils.

kill and get other persons spoils

that is new to me

In fact, if you follow the log, Muleyak should have by the time 4 spoils (not troops). So it should be 1 set + 1 spoil max. And he played 4 set (12 spoils) on round 9.

I`m not talking about the number of troops, but about the number of spoils. How can you get 12 spoils in 9 rounds?
