Dominion Dismantle Promo

– Trashing is not optional.
– If you trash a card costing $0, or if you have no cards left in hand to trash, nothing else happens.
– If you trash a card costing $1 or more, you gain a cheaper card and a Gold. Both come from the Supply, and are put into your discard pile. The cheaper card goes into your discard pile first. For example, if you trash a Silver (costing $3), you could gain an Estate (costing $2).
– There will almost always be a cheaper card in the Supply, since Copper and Curse cost $0, but if there aren’t any, you still gain a Gold.
– If there aren’t any Gold left in the Supply, you still gain the cheaper card.
– Cards that cost only P (like Transmute from Alchemy) or only D (like Engineer from Empires) do not cost $1 or more.

Other clarifications (from wiki):

– Cards that cost P or D plus some amount of $, like Apothecary or Fortune, do cost “$1 or more”. For instance, you could Dismantle a Fortune and get a Province and a Gold, or an Overlord and a Gold.
