I am -- to be perfectly honest -- not that into art, and I tend to read card text much more carefully than I examine the art. But! Even I do appreciate cards that are pleasing to the eyes, and with that in mind I'd like to start a thread for us all to mention some of our favorite card art.
I'll list some of my favorites by card type. Feel free to follow suit or just chime in with whatever you'd like to say.
Favorite hero art: Aragorn (Lore), honorable mention to Beregond.
Ally: Descendant of Thorondor
Attachment: Ever My Heart Rises. Honorable mention to Dwarven Axe, but only after somebody pointed out that you can see a dwarf's reflection in the metal. Like others, I thought this was a bloodstain before looking more closely at it! I kind of life Thror's Map as well.
Event: A Watchful Peace, Short Cut
Enemy: Moutain Warg (Misty Mountains set)
Treachery: A Chance Encounter (Deeps of Moria set) -- this one makes me chuckle
Location: probably the hardest category, with some many good choices. I like Lake in the Cavern (Dugeons Deep and Caverns Dim) & Ithilien Road (Into Ithilien)
Objective: Shadow Key (Escape from Dol Guldur)
Treasure: Bilbo's Magic Ring
Quest card: Approaching Cair Andros (Siege of Cair Andros 4) and TEndless Caves (Foundations of Stone 4B), the latter being very thematic. I also want to mention Ambush on the Shore (Journey Down the Anduin card 3).
Ok, your turn!
