Created for Challenge # 031. Battlefields are specific fields of battle where side fighting can occur. Players assign creatures to either the Tombs (in this isntance) or to the main battlefield (originally called "in play"). Creatures can only block other creatures at battlefields that they are assigned to... though, any player can block any creature to help deal with the amount of creatures that got a boost from Rushing River technology.

Admittedly, that's probably not the best execution. I'm sure that if I worked on this, I'd find a better way to do it. I also tossed around the idea of the battlefield having a pseudo-loyalty counter thingy going on, with the person who got the needed amount of counters claiming the battlefield, but that's a different pile of problems.

I really like the idea of multiple battlefields, though. It's something I've toyed with in the past.
