The issue of discarding cards ad infinitum I think ought to be addressed before we go with that ring. I don't think a Ring should let you dump your hand whenever you want.
Agreed. That's why I think the "...if bearer is not wearing The One Ring..." is needed.
By the way, I have tried out this ring (discard 3 cards) against a couple decks (Sauron Trackers,
Worry Uruks). The ability/decisions/tradeoffs are pretty solid. I like the fact that often when deciding to put on The One Ring that you need to consider that discarding the cards in most cases will cause you to lean towards not moving again. You have to decide which is more important.
Here's another thing that I liked as a decision it forced me to make: Do I have the Ring-bearer take the archery wounds (as burdens) and therefore have to discard a couple of key skirmish events, etc., or do I have my main fighters take the archery wounds and keep the skirmish events to help them win their skirmishes?
All in all. I like this one.
