Discarding and Scholar's new power:
1. Is the wording "Player discard" the key, for example Consider the Price of Victory tells players to discard a card, would that be the Scholar discarding and therefore count for Channel? This seems to be the idea.
2. Would river of lava count for Channel even though it discards from your deck? I assume yes here as well.
3. Does this ruling affect how Police backup is destroyed? For example if missing resources only discarded the revealed card, would police backup remain in play, since the villain did not make a player discard, but discarded the revealed card herself? I assume it would count the same cards that Channel would.
Assuming I am right in how this works, here are the non-hero cards currently out for SotM whose discard will not count towards Channel. *=by villain, so relevant to Police Backup.
Already in video game
Realm of Discord: Ghostly Images
Ruins of Atlantis: Atlantean Font of Power (I would assume anytime a duplicate limited card would be put into play, the discard by rule would not count toward channel)

-----
Freedom Tower: Dr. Stinson's lab: It does not say player discards, but it is optional, and obviously the player is choosing. The understood "you" should be enough for it to count for Channel.

Argent Adept: Inventive Preparation: This one works similarly to Stinson's lab, the player looks at the top card, but the rest of the command says to replace or discard, I assume it is still the player, so it would count.
