I didn't necessary ask for a "Solo" deck, but for a deck centered around Bilbo or Smeagol as ring bearers.
I just went through all 
![Shire [Shire]](https://lotrtcgdb.com/forums/Smileys/classic/shire.png)
 cards in the movie block, and what I think could be interesting cards for a real Bilbo Solo deck are:
Allies:BounderHobbit Party GuestIn addition to their special abilities that are very useful, these allies add Hobbits to spot for 
Chance Observation and you can use them with 
A Marvel to pump Bilbo. They are not unique, thus you can play up to 4 each.
I also thought about 
Goldberry, River-daughter and 
Tom Bombadil, The Master but they are really too expensive for such a deck, unless you have cards to remove twilight, like 
the Gaffer's pipe with other pipes/pipeweeds. Pipeweeds are great because they are possessions, much harder to discard than conditions, but they take a lot of room.
Possessions:Brace of Coneys (to remove the burdens added each turn)
Hobbit SwordOrc ArmorConditions:O Elbereth! Gilthoniel!The Tale of the Great RingConsorting With WizardsStone TrollsCliffs of Emyn MuilEvents:Chance ObservationHalfling DeftnessHobbit AppetitePower According to His StatureClearly, this lacks a lot of burden removal... And maybe recycling of essential cards like 
A Marvel or 
Chance Observation. 
Birthday present? Adds even more burdens.
You would also need to draw as quickly as possible 
Consorting with Wizards to make Bilbo invincible...
For that, there is also the possibility to "cheat", play 
Gandalf, Leader of men and 
Sam, SOH in the starting fellowship and fetch those cards with 
saved from the fire... But this adds even more cards to choose from...
Ideas?
