Easily one of the best cards in the game, if not the best.

Can two of it boost the same character in single challange? 

Sure.

Generally speaking, each ability in this game is treated as a separate effect. Using two of these on the same character in the same challenge creates two individual "+1 STR" effects that would be applied and resolved separately, giving a 1+1=2 overall result.

Because the two effects are separate, they are not considered to "do the same thing," so it's not like the first gives +1 STR, then the second tries to do the same, but fails because the first already did it.

Thanks, I thought so. 

Then, I think it should cost something or be at least limited. Non uniqness and 0-cost makes this card very powerful. Especially in opening rounds. One might thing that it is dangerously close to being overpowered. Comparing Castle black, which has advantage that stands character, it is still better, much better.

I see the difference though. Casle Black serves The Wall and this serves only winning one challange. It can push oponent to attack with greater power though.

I really do think that this is close to being the best card in a core set only environment. It works off of attack or defend, it's a zero cost, non limited card for set up, it works extremely well within the context of the house as well. It's just a ridiculously good card compared to a lot of other effects.

Every house has cards that are very agressivly costed. Castle Black for example can stand a 3 cost character and you gain a tempo advantage far superior than you get with this card. Only time will tell if one of the cards is really too good.

Castle Black is also a unique 2 cost location. As opposed to a zero cost non-unique location.

So what? If you stand a 4 cost character, you get your 2 str boost and you can use your 4 gold character again, despite the you payed only 2 gold for the location. And if 2.0 pans out as 1.0, being unique will be a boon, because it will have immunity against some nasty effects.

I am not looking at how it pans out. I'm looking at the limited card pool of the core set by itself.

Unique means you can affect one challenge a turn. You can affect potentially 3 challenges a turn with this location. Also, it is much easier to play this during set up since it literally costs you nothing.

Castle Black is a great card! It's amazing! It's not as good as this card.

You can only affect 3 challenges, if you have drewn and played this card 3 times. The setup is a plus for this card, but the cost to effect ratio is much higher with Castle Black. So saying one is better than the other isn't working for me, because these cards are in different factions with different synergies, different costs, different effects and different applications within their factions.

Then how about the statement, This card helps to reinforce the decks and strategy of said decks in its faction more than almost every card in other factions in the limited card pool that is the 2.0 core set.

Definitely one of the best cards in Core, it's absolutely ridiculous.  If it was unique it would be ok but once your opponent has two out it becomes almost impossible to fight against.  All your tools are against characters but now he doesn't have a strong character you have to kneel/stealth, he gets to make them strong after your evasion and tricks.

Castle Black - Unique, 2 cost, works only on defense, no synergy buffs
 

Iron Fleet Scout - non-Unique, 0 costs, works on attack and defense, synergy buffs Drowned Men

So aside from Castle Black being significantly worse in all respects they're about equal

Love these ships. Want more ships!

@Magicdave: That's a bit of an over-reaction. Castle Black also stands, which is a very powerful effect, and the stand-on-defence has massive synergies with the Night's Watch's defensive stuff, like The Wall.

Iron Fleet Scout is a great card, but if you're talking strictly effects Castle Black is definitely not weaker. The only thing that knocks Castle Black down is that it's unique, and costs 2. If it was non-unique and had the same cost as IFS, it'd kick IFS's butt.

But fact remains that Castle Black is unique and cost 2, so there's no way that it's equally as good as Iron Fleet Scout which is non unique and you can put all 3 in play at the same time, for free.

It's true that Castle Black isn't as good as Iron Fleet Scout

But it's also true that Castle Black isn't "significantly worse in all respects"

They're both good cards. Iron Fleet Scout is better. Castle Black still doesn't suck.

Quick question on multiples of these and where you can add the STR. I suppose this applies for all STR buffs from cards.

Say I have two of these.  Scenario:

I'm first player, I'm using Balon (core). There are a few standing 4,5,6 str chr's and one 8 Str chr oponents side, but I don't want to go all out and double buff him right away because I don't know what he will kneel, so I choose to do one buff first by kneeling one Scout, taking Balon to 7, thus covering myself if he uses the 5 and 6 str'ers

He decides to put the 8 STR chr in. So now I use the action window following defenders, to kneel my second Scout and buff Balon to 9, meaning his 8 str chr doesn't contribute it's str.

Is this correct, can I use the str buffs in two seperate action windows of the same challenge?

Alternatively, it would also be ok to kneel Balon with no buffs, then use both buffs together in the action window after he declares ?

All of those described work. Any action may be performed in any window it is eligible for, and any number of actions can be performed in that window.

One of the few cases I can think where I wouldn't leave it for after defenders would be with core Catelyn around. Otherwise, I'd wait for them to maybe make a play and use characters that won't have an impact.

Thanks. Good point on Core Catelyn
