I'm curious about all of what this entails. The rulebook says it means that teams have to communicate, can only have one copy of a unique object in play (per team not per player), and that the rule about enchantments applies the same as always.
If the rulebook was merely saying that each team can only have one copy of a unique object in play at a time, then why didn't they just say that? Do teams have unified spellbook building, like not having more than six copies of a level 1 named spell in all the team's spellbooks combined? What about cards that would return a card to its owner's spellbook, like jinx? Can they choose the spellbook it returns to since all the players on a team are treated like one player? What does it mean to be treated like one player? I feel like I'm missing a lot of info here.
Thanks!
