Shadows cards and "printed cost."

By King of Thorns, in 2. AGoT Rules Discussion

When a card's rules text refers to "printed cost," how does this work with cards that have an sX cost? Would a card with a cost of s2, for example, be eligible to be grabbed by Maegi's Promise or Bran the Builder's Legacy?

The printed cost of a shadows card is the sum of the X part in sX (the cost of the card) plus 2. A card with a cost of s2 has a printed cost of 4.

And just in case you're wondering where this information is coming from, it' can be found in the Shadows rules document that's in every one of the King's Landing chapter packs and can also be found in the support section of this site.
