Discard 2 cards. Each other player may reveal a Bane card from his hand. If he doesn't, he gains a Curse.
Setup: Add an extra Kingdom card pile costing 2 Treasure or 3 Treasure to the Supply. Cards from that pile are Bane cards.
Each other player reveals cards from the top of his deck until revealing one costing 3 Treasure or more. He trashes that card and may gain a card costing at most 2 Treasure less than it. He discards the other revealed cards.
