Seems like some of this contract is ambiguous to me. So I have a few questions:
1) "The attachment must be an artifact or item." Is that attachments with just the artifact trait, the item trait, and the artifact and item trait (40 possible attachment cards). Or is that any attachment with the artifact or item trait, and we don't care if it has any other trait (armor, weapon, ring, staff, master, ent, instrument, pipe, trap) so long as it has artifact or item traits (99 possible attachment cards)?
2) "If that attachment has the guarded X keyword, ignore it." I believe the guarded X keyword is only found on 7 cards (Glamdring, Mithril Shirt, Necklace of Girion, Orcist, Ring of Thror, Sting, The Arkenstone). So for the 14 attachments that we pick that are artifacts or items, they basically all gain the Guarded (location) text to them? We ignore if it says Guarded (enemy) or Guarded (location or enemy)?
3) Does card text still come into play? As an example, if we are able to include Narya, Nenya, and Vilya to our loot deck (Artifact. Ring. traits), do they still have to be played only on their named Heroes? Sting on a Hobbit (Artifact. Item. Weapon. traits)? Etc.
4) "You cannot include attachments in your deck." Can we still start with The One Ring attached to a character since technically it isn't part of the deck? Or would we add The One Ring to the loot deck (Artifact. Ring. Master. traits)? It has a Setup to grab a Master card. Does that mean we can't play the new Inner Strength attachment (Master. trait) with this contract? The Inner Strength attachment card fits the bill of being a Master card that can be selected during Setup. And if The One Ring has to be included in the loot deck, does the Setup part still apply once it is played (Look for Master card)?
