To answer both questions.





1. It just says Monster Zone, so can be either Main or Extra. If it did specify, would've been noted.







2. It really does say that monsters with less ATK than it can't attack or activate its effects. So yeah, also locks you out of anything under 2000 ATK (which does include the new Slime monsters that original God Slime came with).







Considering it also doesn't specify the field, might affect hand traps too for activating effects.
