I am waiting till the cycle is over to have a new article ready but I just wanted to share a few thoughts about the Sons of Elrond.
Initially I was pretty disappointed but I grew to like them of course (after having made much effort to deckbuild around them).
What I find interesting is how different their effects can be. I mean they look similar on paper but in practice I tend to think Elrohir's is much more useful, especially in conjunction with Arwen. Of course you still have to overcome some terrible shadow lurking but Elrohir really is a wonderful defender. It is a very satisfactory feeling to block so many enemies without being hit. And to do so against a Troll without Protector or Warning (just with the help of his Sister, or a mere Blade Mastery) is great. And when I finally succeeded (upto a point) in making a good deck around the Brothres, I tried to go as easy on Leadership cards (and their cost) as possible just to be ready to do more defending on an average round without the need to put any resource acceleration on Elrohir. For the ability to ready is good even when he doesn't need to defend twice, just to hit back at the enemy.
Well, Elladan isn't that flexible. So when I need to quest with either of them, he's always the one. But then again, when I have a Courage at hand, I often play it on Elladan, so that he quests and is ready to deal blows. Also, Elladan is the one with the card synergies of the likes of Rivendell Blade, Bow but even cards like Quick Strike. Of course Elrohir can make use of the Signals but I really find the Warning not a good choice to fill a valuable card slot.
As for the art, I think Elrohir looks much cooler.
As a subplot to this thread, I like how the Watcher of the Bruinen and Trollshaw Scout are made in a similar way to the Brothers. Not that I would probably play them in the same deck but they resemble the more powerful heroes in their opposing abilities. And contradictory to the above, from the two allies I much prefer the attacker.
