You get many draws. I hardly had any.

When white had 3N+C vs black 3C+N (setup below), white won 101 games, black 26, and 1 draw (79.3%).

With reversed colors black won 73 games, black 20, and 3 draws (77.6%)

Total result: Nightriders vs Cannons 176-48 (78.6%). Statistical error 3.3%.

I used C=350, N=460, Q=851, Half-Mao = 74. In my experience there are no self-fulfilling profecies here: if you let the engine believe the wrong piece is the more valuable, the better piece would still win. Because no matter whether their believe is correct or not, one of the players would still avoid they would be traded for each other. So the imbalance stays around a long time, during which you measure how much damage the pieces do to others. (Unless you go to extremes like Pawn > Queen, then it will of course quickly sac its Queen for a Pawn, as Pawns are way to weak, abundant and exposed to avoid such a trade.)

In fact the performance of the piece that the engine thinks is most valuable would suffer from this, ('leveling effect'), whether the believe is correct or not. Because its deployment will get hindered by the need to avoid 1-1 trades, from which the piece that is believed to be worth less does not care about that.
