Sure you can use smeagol gametext, but unfortunately he doesn't get the str-bonus.
First time I played I gave to much twillight, but after that I didn't gave more then 8 for the shadow, but then I still had either Sharku, Warg-captain + Sharku's Warg + Isengard Axe or Foul Horde + Isengard Axe + Warg, against me. Believe me Dear Friends doesn't help on site 2 against a damage +1 fierce minion; it meant that each time on site 2 there were 2 comps dead: Frodo and Smeagol.
Again, Smeagollum, I think you are missing the point. I keep saying this because of responses you made earlier about how losing 20 cards to discard would mess this deck up. The point is that YOU will discard your ENTIRE draw deck at site 1. Therefore, you are relying on Freeps to win unless you get a couple key Shadow cards. Also, you can draw whichever cards you need. I don't see how the Shadow would be useful in other deck types.
IF you can survive site 2--and I admit that it is a challenge--you should be OK vs. Wargs on site 3. The aforementioned combo of two wargs + riders won't happen at site 2 (not enough twilight). Since you have 8-10 cards to ditch from your starting hand if needed, Smeagol can fight at least one because even IF they cancel a bunch of discards, you can still be strong enough. Let's say str 14 rider... cancels 4 of your discards, but you still have enough to make Smeagol str. +6 or 9 vs. 14. Then they have an exhausted, non-fierce rider.
If you kill off Smeagol, you ruin the entire deck! Better to kill Gimli even -- at least there is another dwarf coming! Killing Frodo and Smeagol is basically conceding defeat. Anyway, if I knew I was playing vs. Wargs I'd probably try something like:
Aragorn, Ranger of the North,
Aragorn's Bow,
Greenleaf,
Aiglos,
Eowyn LoI,
PreparationsFor site 2-->3. Risk Enquea and exhaust a
warg with archery to kill with
Eowyn LoI. For example: two vitality 5
warg riders. Hit one of them four times and the other twice with archery. Exhausted rider on Eowyn, exert for 4 wounds on Shadow. Total 10 wounds = both die. Or maybe
Greyhame +
Roll of Thunder instead of
Aragorn's Bow +
Aiglos.
Why would Gandy cards in your hand hurt after mulligan? Discard them all. Also, the potential str+3-ish bonus from
Axe of Erebor doesn't make it worth a card slot as Gimli isn't a fighter in this deck.
Gandalf's Staff is good for emergencies...
Axe of Erebor just gives a mediocre fighting companion. You won't get it in time to face the wargs anyway.
(BTW, lack of a strong starting companion was the reason I wished I could keep using
Beneath the Mountains...

I would have used
Dwarven Axe, though)
