Looks pretty good! You need to specify where to stack the card FROM, although I assume you meant from your hand. I like the card, but I think it could be unique. It might be too powerful with 4 out. That could be +12 strength and the ability to take any of those cards back into hand. For example, I’d always use this with They Stole It to get tons of cards to discard.

You need to say where to stack the cards from. Also limit 3 means that you can only stack 3 cards here per phase, but without a limit overall. If you mean that it can only have 3 cards, it needs to say Maneuver: If you can’t spot three cards stacked here, stack a...

Otherwise this looks fun and potentially powerful.

Dáin’s DC Duos #44

•Wretched Oddments
Possession • Support Area
Discard this possession if you cannot spot another card.
Gollum is strength +1 for each card stacked here.
Maneuver: Spot less than 3 cards here to stack a card (except a minion) or Shadow possession here from hand.
Shadow: Remove to take a card stacked here into hand.
“...fishbones, goblins’ teeth, wet shells, a bit of bat-wing, a sharp stone to sharpen his fangs on, and other nasty things.”
it does the job.its somewhat dubious whether all that would fit on a card. maybe make it limit +3 and cut from Spot to to.

•Gollum’s Boat
Possession • Support Area
Gollum is vitality +1.
Each time Gollum wins a skirmish, add a token here (or 2 tokens if that skirmish involved a Ring-bound companion).
Shadow: Remove 2 tokens from here to play Gollum from your draw deck or discard pile.
“He had a little boat, and he rowed about quite quietly on the lake....He paddled it with large feet dangling over the side, but never a ripple did he make.”
I like it.

Cross It Is
Event • Shadow
Exert Gollum to play a possession from your draw deck. Unless the Ring-bearer is a Hobbit, that possession’s twilight cost is +1.
“‘...impatient, precious. But it must wait, yes it must. We can’t go up the tunnels so hasty. We must go and get some things first, yes, things to help us.’”

no I am saying limit +3 strength. the shadow possession part could be cut to.

Inquisitive and Curious-Minded
Condition • Support Area
Each time the fellowship moves to a river or forest site, you may add a threat to heal Sméagol.
“He was interested in roots and beginnings; he dived deep into pools; he burrowed under trees and growing plants; he tunnelled into green mounds; and he ceased to look up at the hill-tops, or the leaves on trees, or the flowers opening in the air: his head and eyes were downward.”
really nothing to say very basic card.

Land of the Stoors
Condition • Support Area
Discard this condition if you cannot spot Sméagol and Déagol.
Each site on the adventure path is a river.
Maneuver: Discard this condition to make the move limit for this turn +1.
“Long ago, on the banks of the Great River, lived little Hobbit-like people. They loved the river, and often swam in it, or made little boats of reeds.”
the manuever ability should probably cost more. make it discard it and exert smeagol twice or something like that

Memories of Ages Before
Event • Maneuver
Exert Sméagol to discard a Shadow card (except a minion).
“...when he lived with his grandmother in a hole in a bank by a river. ‘Sss, sss, my preciouss,’ he said. ‘Sun on the daisies it means, it does.’”

Hm...good card. May go in some IB decks with Smeagol.

Man that’s mean. No worse than that condition that makes each site a battleground, though.

Nice. Good-bye Shelob, Eater of Light! (not the minion, but the whole support system). However, isn’t it rather specific? Maybe add a choose one kinda thing, and give it a more generic option. Maybe a condition of Shadow card? Oh, BTW, why does it have to be shadow? If someone wants to chuck some of their own cards, let em.
