it works like complex numbers in mathematics do.
Not sure what you want to say, but complex numbers and ordering don't mix. It is not true that 1 < 1+i or something like that. They are *all* incomparable. That's different from Dominion, where *some* card costs are incomparable (2P and 3) while others are comparable (4P and 3). The mathematical term for that is a partial order.
