Silvan Tracker is not as good as it could have been. It's statline isn't very good for it's cost and it's ability is limited by the fact that you don't want Silvan elves taking damage in the first place. Now, granted, if you can get one to survive an attack or two, then you really want this up and running. With multiple copies out, they could defend and then heal each other. A better option would be Galadhrim Healer. Of course, just for fun, you could get extra healing out of this by exhausting a hero for Captain's Wisdom say; and ready it again with Heir of Mardil or something like that!

Response: After a Silvan character readies during the refresh phase, heal 1 damage from that character.

The Silvan Tracker's Response only applies during the Refresh phase, so it doesn't do anything with your suggested Captain's Wisdom/Heir of Mardil combo. — Warden of Arnor 3375
Whoops! I didn't realize Captain's Wisdom was a resource action. Thanks for the heads-up! — Wandalf the Gizzard 1034
