Do regions still work?
Earlier discussion in this thread concluded that the reason you could only have one region in a server even if no card with the text “Limit one region per server” was active was that the rulebook said so.
I just went to look this up because regions came up in a Reddit discussion, and it looks like none of the current rules documents (LtP, RRG, FAQ) have the word “region” anywhere (except on a card shown in an example).
Given this, is it now legal to have multiple regions in a server, so long as no regions are rezzed? If not, why not?
