For tournament play (Grand Kotei, World Champinships, etc.), I know that I need to have my Conflict and Dynasty decks in opaque matte sleeves. What about cards that are not shuffled?
Province Cards: Currently I'm using thematic sleeves with art on the back (specifically, these sleeves). Permitted?
Stronghold: It's always face up and never shuffled. Currently using the same art sleeve if only to keep it safe.
Role Card: It's always face up and never shuffled, although I suppose the other side could be confusing. Currently using a clear sleeve.
Imperial Favor: Currently using a clear sleeve.
Rules Reference Card: Currently using a clear sleeve.
Thanks for your help!
