This card is WAY overpowered. It turns unplayable cards into massive attack. The bonus damage is fine for rares, but it's too high for uncommons and commons. It should be 5/10/25 IMO.

You might be right, but don't underestimate the value of a turn you spend discarding.

I don't think you're wasting anything. You're basically playing a 0 cost card that adds damage to your next turn. You're still getting production and you can still draw a rare. All-in-all, it's a solid trade for adding a lot of damage.

It's still a turn to brace for impact, in some situations the other player can abuse the 'anouncement' of the discard to force the Vulture player to work on his defences, or timing the discarding of Vulture (Intrigue or so) in such a way that the discarding is still a mere loss of time.
