So if I'm reading this right, we have...
Lore Saruman (woot woot)
Lore ally (2 cost, 2, 2, 2, 2)
Lore ???
Spirit ally (2 cost, 1, 1, 0, 2)
Spirit ???
Leadership event (0 cost)
Leadership ???
Tactics attachment (0 cost)
Tactics ???
Neutral attachment (2 cost)
My guess is that artwork is for the contract. It could very well be art for any of the four remaining cards but if anyone can go it alone, it would be Galadriel!
Well done! Cannot wait to try these cards some time in 2021!
