I have some questions about the game:

1. If I start a millitary challenge with Syrio Forel: "Response: After you win a challenge in which Syrio Forel participated, put him into Shadows." and my opponent uses his Field Spikes: " Challenges: Kneel Field Spikes to choose an attacking character with STR 2 or lower. Its controller chooses either to remove that character from the challenge, or to kill that character after the challenge resolves. " and i choose to kill Syrio, could I activate his response to bring him to the shadows before he's killed? Does it depend of who is the first player for responses order?
2. If I activate Margaery Tyrell's ability: " Response: After a card comes out of Shadows, choose a non-Lady character. Until the end of the phase, treat that character as if its printed text box was blank. " and my opponent uses Lost Oasis: " Challenges: Kneel Lost Oasis to choose a HM character. Until the end of the phase, that character gains Stealth and "after this character bypasses a character by using Stealth, kneel that character." ". Does his character gain Stealth and the ability or Margaery still blanks his text box?
3. What is text box considered? Passive abilities? Triggered effects? Traits? Renown, Lethal...? Influence and gold producing icons? Crests icons? Challenge icons?

Thanks

1. I'm going to steal ktom's outline of the challenge resolution framework action window here:

Step 1.1: Initiate "Determine winner of challenge" by comparing total participating STRs.
Step 2.1: Save/Cancel "determining the winner"
Step 3.1: Resolve "determine winner" / challenge officially won

Step 1.2: Initiate "Settle claim effects"
Step 2.2: Save/Cancel vs. "Settle claim effects"
Step 3.2: Resolve claim effects

Step 1.3: Initiate "Award unopposed"
Step 2.3: Save/Cancel "award unopposed"
Step 3.3: Resolve awarding unopposed / power officially claimed

Step 1.4: Initiate "Award Renown"
Step 2.4: Save/Cancel "award Renown"
Step 3.4: Resolve awarding Renown / power officially claimed

Step 4: Passives (including Deadly) to anything above

Step 5: Responses to anything above

Step 6: End (remove moribund cards)

The kill effect of Field Spikes is a passive effect so it happens in step 4. Syrio's return to Shadows effect can be triggered during step 5 along with all other responses to the challenge resolution action window. So Syrio will be Moribund by the time you would get a chance to return him to Shadows.

2&3. I'll quote you the relevant passages of the FAQ here:

(3.8) Gaining Abilities
If any card effect has the text "character
gains...," any ability (traits, keywords, icon
modifiers, or STR modifiers are not considered
abilities) following the word "gains" is consid-
ered to now be a character ability. However,
that effect is not assumed to be a part of that
character's text box. Any effect that blanks a
card's text box is assumed to blank that card's
printed text box.
(3.9) Icons in the Text Box
Gold modifiers, influence, and initiative modi-
fiers are not called out with an outline, and are
therefore a part of a card's text box. Challenge
icons and crests are differentiated from the text
box of a card by a solid outline, and therefore
are not considered a part of that card's textbox.

So the text box includes traits, keywords, any abilities (any words other than flavor text, traits, or keywords in the text box), and gold/influence/initiative modifiers.

Also, to be clear, the character still gets the stealth and the ability because of 3.8 above.

Ok, i understand it now, thank you!!
