Rezoning - $3
Action
Reveal cards from your deck until you reveal two Victory cards. Put those Victory cards into your hand and discard the other revealed cards. You may return any number of victory cards from your hand to the Supply, and gain a Victory card costing up to the sum of the costs of the cards returned.
I have no idea about the balance of this, but I like the concept. An interesting variant on Forge.

+2 Cards

When another player plays an Attack card, you may reveal this from your hand and discard it. If you do, +2 Cards. You may choose to resolve this effect before or after the attack finishes resolving.
Off the top of my head, I can't think of good reasons to give that choice. Resolving after an attack finishes should almost always be better. For most attacks, it wouldn't normally matter (various edge cases aside such as reshuffling to draw the 2 cards). For discard attacks, you would want to draw after. And the "resolve this later" clause isn't really well-defined in the game rules, you can't finish resolving a card during a later time like that. I would probably just use the Horse Traders "set aside and draw on next turn" wording.

When another player plays an Attack card, you may reveal this from your hand and set it aside. If you do, +1 Card. At the start of your next turn,+1 Action, and return this to your hand.
"When another player plays an Action card" is a bad event to have a reaction to. It means that in games using this, players need to play their actions cards extra slowly, to give time in between each one to see if you are going to react to it or not.
