A - Eleanor - close call too, I love both, but I fell in love before with my treachery-eraser cheek
B - Mirlonde - she's one of those heroes that I think that shines more than most people think
C - Pippin (Lo) - clear choice for me!
D - Bilbo Baggins - every time I see his illustration, I can't help but smile. Besides he's of tremendous help in solo!
E - Faramir - one of my favorite heroes!
F - Glóin - I used him so many times at the beginning...
G - Háma - Never used him (I am more Leadership/Spirit/Lore player) but he's a really cool one. Besides, Magali...
H - Nori - Nice for alternate dwarf decks (not the classic Thorin & Co. one). And is like Bilbo when looking at the illustration, smile!
I - Bifur - Well as you can see I am a dwarf lover...
J - Denethor - ...but in this case, I prefer the Steward of Gondor!
K - Hirluin - Love the art, and how he changed Outlands (well, him and the entire player card pool from SF)
L - Frodo - Easy call here, even with Magali on the other side!
M - Théodred - That's the other hero that I used a lot the early days!
N - Merry - Really, really nice card
Well I am a dwarf and hobbit lover as you can see. And of course, Magali illustrations are top notch! But I tried to choose not only by art, but by usefulness and theme. Well sometimes by fond memories .
