- Trash a card from your hand.
Gain a card costing exactly 1 Coin more than it and a card costing exactly
1 Coin less than it, in either order, putting
them on top of your deck.
- First trash a card from your hand, if you have any cards in hand. Develop itself is no longer in your hand and so cannot trash itself (though it can trash other copies of Develop). If you trashed a card, gain two cards, one costing exactly 1 Coin more than the trashed card, and one costing exactly 1 Coin less than the trashed card. The gained cards come from the Supply; gain them in either order. lf there is no card in the Supply at one of the costs, you still gain the other card if you can. Put the gained cards on top of your deck rather than into your discard pile. If you trash a Copper with Develop, which costs 0 Coins, you will try and fail to gain a card costing -1 Coins (and also try to gain a card costing 1 Coin).
