From all cards in core set, this is the one, why I, as solo player, want to try multiplayer game. I like the effect, I love the artwork and imagine to have six of those in two decks in four player game, sounds like great opener for the battle. Sounds epic, but I can't say yet. We'll see.
Rain of Arrows
Action: Exhaust a character you control with the ranged keyword to choose a player. Deal 1 damage to each enemy engaged with that player.
Core Set #33. Tactics.
Rain of Arrows should have been named rain. A resource, an exhaust, and a keyword restriction for just one damage per enemy for one player? Even Skyward Volley and Hail of Stones are better than this.
