My brain is a bit too frazzled at the moment to make changes to the previous cards. Hopefully I'll do something about them soon.
I understand how that goes, so some advice: perhaps just make it so that each time you play
Persistent Villain from the discard pile (or perhaps just "except from hand"), you get to add a threat? That would make him MUCH more viable.

Leap from the Shadows
shadow
Event • Skirmish
Return - exert Gollum.
Spot Gollum to make a minion strength +2. If you played this using the return cost, remove this card from the game.
The only problem I see is that it's a LITTLE too good compared to cards like
Hobbitses Are Dead (more specific),
No End of Wickedness (requires exerting), and
Cunningly Hidden (which can also be pulled back, but costs
![2 [2]](https://lotrtcgdb.com/forums/Smileys/classic/2.png)
). Perhaps raise the cost to
![2 [2]](https://lotrtcgdb.com/forums/Smileys/classic/2.png)
and make the strength boost +3. I'd like it a LOT more then. It's okay now, I would just like
![2 [2]](https://lotrtcgdb.com/forums/Smileys/classic/2.png)
/+3 a little better.

Dark Allies
Shadow
Event • Skirmish
Return - ![3 [3]](https://lotrtcgdb.com/forums/Smileys/classic/3.png)
Spot Gollum to make a minion strength +1 for each Shadow culture you can spot. If you played this using the return cost, remove this card from the game.
Nice. Again,
![2 [2]](https://lotrtcgdb.com/forums/Smileys/classic/2.png)
might be better, afterwhich you could reduce the
return cost to
![2 [2]](https://lotrtcgdb.com/forums/Smileys/classic/2.png)
.

If a
minion has just won a skirmish against a companion, spot an
or
minion to discard that companion.
"She jabs them with her stinger and they go as limp as a boned fish. Then she has her way with them."
I think the wording should be "If a
![Gollum [Gollum]](https://lotrtcgdb.com/forums/Smileys/classic/gollum.png)
minion wins a skirmish, spot an
![Orc [Orc]](https://lotrtcgdb.com/forums/Smileys/classic/orc.png)
or
![Uruk-hai [Uruk]](https://lotrtcgdb.com/forums/Smileys/classic/uruk.png)
minion to discard a companion in that skirmish." It's awesome, and I LOVE the synergy, but it should probably cost a lot more, like
![3 [3]](https://lotrtcgdb.com/forums/Smileys/classic/3.png)
or so. Maybe not...kinda unsure about this one. I'd wait and see what other reviewers think, but that's my gut reaction.
