Plants are nice. But don't offer the challenge a human opponent does. You know something funny? The idea of a "metagame" is often relegated to referring to video games. But it in fact is very important in strategy. In fact it's one of the first things you should learn, as everything in the field uses the basic ideas of simply knowing what your opponent will do.in fact, without a mastery of said metagame you might as well throw in the towel, as at the end of it all the one who controls the meta controls the battle.
