I also have to deal with that because I usually play against my younger sister. Although she is getting better I still try to build more complicated decks for me to use, that are either very combo reliant or just plain hard to play. That way I give myself some handicap without making her mad by giving her blatant advantages .
I like to use Torquemada Coteaz for that purpose since he requires a lot of precision play and attention to work properly.
I´m afraid I don´t have insight deep enough to build such decks properly, still new to the game and it´s hard to predict how some deck will work. I tried to ask for weaker warlords earlier but sadly it seems that this game is well balanced
Kaloo - Nice idea, it´s really worth trying. Maybe -1/-1 at start and then use your change.
We tried a game with -2/-2 yesterday and it was good - I had really bad start due to this change, lost the first planets almost without fight and had to build around later planets since beginning to get some resources instead of my starting ones. -1 resource later helps weaken me when I build my position... thanks for advice
