Plot cards?

By Steelemdv94, in 4. AGoT Deck Construction

How many copies of a card can you have? Some say only play 1. Some say you may play 2. Just curios about the ones that say nothing about deck construction.

^ Copies of plot cards.

Only 1 unless stated otherwise.

The cards that state only one(Valar Morghulis) is a leftover restriction from the CCG format where the deckbuilding rules were a bit different.
