I guess if you have skirmish pumps in hand and your opponent plays a bunch of low-mid tier minions
Pretty much. You're meant to assign the minions such that the difference in strength between all characters is minimal, then have a pump push you over the edge. But it's really weak. Even reinforcing doesn't help it much.
Mordor Enraged, anyone?
I hate those kinds of self-defeating cards. The more archers they have, the fewer wounds I want! Only use of that card I know is to play it on Sauron.
I was reminded of
Despair recently too. The number is so steep: 3 dead guys is one less burden on Frodo? Not to mention you have to hold it in hand.
