Some shadow cards based on the dead marshes (aka the Sauron twilight minions) with the basic strategy of lowering companions strength (it just seemed to fit them).

Twilight.
Skirmish: Exert this minion to make a companion skirmishing it strength -2 (or -4 if you spot two other Twilight minions.)
add enduring as Macheteman said. if you did that it could be quite good. maybe even make it vitality 3, and strength 4

*Dead Men, Elves and Orcs
Minion • Wraith
Strength: 4
Vitality: 4
Site Number: 4
Twilight.
This minion is strength +1 for each other Twilight minion you spot, and each companion with resistance 2 or less.
Skirmish: Exert this minion three times and spot two other Twilight minions to make each companion skirmishing this minion strength -1 for each twilight token in the twilight pool you spot (limit -5).
worse title ever. just make it dead creatures or something. again add enduring,. otherwise pretty good, though I would cut the cost to 4, and make it so you don’t have to spot twilight minions for the second ability. oh even better if you add enduring make it Heal it to trigger that ability but only limit 3.

Add Enduring. Every single wraith D has released is enduring. EVERY SINGLE WRAITH. (Prove me wrong) And have him heal two activate. And the second you get a twilight swarm....maybe stick limit once per phase and -3 for twilight spotting

Huh? Maybe just twilight cost -1 for each companion you spot, nothing dealing with wraiths. Maybe make it and make it heal a wraith, assuming you add enduring

Okay, first off, add enduring for sentimental reasons. And vitality adding...Then make each companion strength -1 for each wound on that companion. Berserker wraith.
