That's how we "educate" new players. And why do you even think I don't know the rules? Do you think I can't remove Martu, or that I only know how to play with Sylvan units? What kind of prejudice is that?
I didn't say you don't know the rules, but in general, before challenging a good player, it wouldn't hurt to show your own skills first, in my opinion. Play a game with a beginner to start. Because there have been many situations where players either abandon the game or start saying nonsense, like "you're a cheater," when they see their opponent has 20 ducks or 5-8 angels on turn two.
Regarding Martu and Sylvan units, I honestly didn't understand what you meant.
