A couple of disclaimers:
1) This is not the same as the sample I gave in another thread; and
2) This card actually doesn't work as written. Miguel says as much in this thread.
There are three problems with River:
1) It doesn't actually work, as mentioned above;
2) It is a blatant exploit to play this on a site nobody is moving to because somebody could potentially move to it. The fact that it can be a dump hazard against squatters as well as effective against movers makes it a sure bet for inclusion in the hazard portion. ICE did not intend it to be a dump hazard and disallowed dumping cards in general;
3) New players are discouraged and disgruntled to find out that their Fallen Radagast, flying around as a bird, will get stopped by a body of water three miles below him.
Therefore:
River
Playable on a company moving using region movement or Under-deeps movement. Target company may do nothing during the site phase. Discard at the end of the turn or if a Ranger in the company taps to discard this card.
Pros:
1) The card will actually work mechanically;
2) The exploit of playing it as a dump card is removed, meaning that it will become great against movers and clog against squatters, as it was intended to be;
3) Tapping the Ranger is made an active condition, so that there is no confusion about what the Ranger must be doing before you can do things during the site phase; and
4) A direct boost to Starter Movement and Special Movement. While River may still affect a player using Coastal Seas, it will at least not affect companies Belegaer or Eagle-Mounts.
I recognize that this one is less likely to be unanimous than the automatic-attack one (which I'm pretty sure everybody hated), but I honestly feel this will be better for new players, for balance, and for the metagame, helping to bring a bit more life to the game.
