Questions about Midnight Sentry,Beric Dondarrion,Lion's Gate, and Devious Intentions

By Aequitas2, in 2. AGoT Rules Discussion

Midnight Sentry: if I have two copies out, do characters with stalwart get +2 to strength

Beric: He can't be killed but can I choose him to satisfy a military claim and therefore lose no one to a military challenge?

Lion's Gate: It says to discard 1 power from any card then give that card a trait of my choice. Since it says any card can I choose an opponent's House card?

Devious intentions: can I put two copies on one character and get double the effects?

Lion's Gate has errata "(v1.3.1) Lion's Gate F17 Should read: "...to discard 1 power from a non-House card in play..."

yes

Please note that even though the character gains the 'stealth' keyword twice, the effect is singular. You cannot bypass two opponents with that character.

The strength boost from Devious Intentions will be doubled, though.

See FAQ page 8, paragraph 3.15: "A card cannot be chosen as a target of effects to hich it is immune".
