Ah, Lobelia. The grumpy Hobbit we all know, accompanied by her trusty umbrella.
Lobelia has 8 threat cost for 1 , 2 , 2 , and 3 . These are not great stats, but they open up great horizons when coupled with her ability. It is also worth mentioning that she has considerable strength for a Hobbit.
Lobelia has the Burglar trait, which does nothing except let her quest without boosting the threat of Smaug the Golden in the Lonely Mountain (and it gives us warm fuzzy thematic feelings). She also has the Hobbit trait, which makes her eligible for cheap readying via Fast Hitch (among other Hobbit tricks). This cheap readying will be important later.
She is in the sphere, which allows her to slot into a Bond of Friendship Hobbit deck if you use Merry. Other than that, she allows you to play Bilbo's Spoons (which is quite thematic).
However, Lobelia's luster is in her ability. She allows you to look at other player's hands whenever you want. She also allows you to pay for Item attachments at any point and attach them to her, even if she is ineligible. These attachments can be in play or in a player's hand (that's how it ties into her first ability).
Imagine this: you are playing Lobelia and hold Sterner than Steel in your hand, allowing you to cancel a shadow effect by exhausting a Weapon or Armor attachment on the defending character. Lobelia is defending, and scrying (such as Spyglass from the Dream-chaser) tells you that she is going to die. You look in another player's hand and see a Gondorian Shield. For one mere resource, you have saved Lobelia from an awful shadow effect.
There are endless opportunities of what to do with Lobelia. You can give her some Staffs of Wizards, turn her into a stalwart defender or attacker, or even steal other people's stuff and give it around the table with Long Lake Trader. Here is my favorite deck using Lobelia as a hero: ringsdb.com by community member Shellin.
All in all, Lobelia is the wildcard hero in this pack. She doesn't seem to fit with the others, but she fits into much more decks: from Hobbits to Eagles to Dale to Grief Decks. Lobelia remains one of the most interesting cards in this pack, and one of the most game-altering that ALeP has produced.
