A few questions:1) Is it a good idea to use Chaos 3 vs Earth 5/Water 5? Or does it depend on Chaos cards? For example, if I have Chaos 8 but opponent can have Air 10, then it is risky so Chaos mana becomes less valuable.2) Is it always a bad idea to start with mana generators vs potential Holy 4/Spirit 4?3) How to deal with Holy 3 protecting mana generators when you don't have Fire 9?
