So, it should be like this.
Angel's Workshop
cost $4 - Action
Gain a card costing up to $6.
Each other player may gain a cheaper card.
At first, it was $3. It looked like a Leprechaun variant. Soon I realized it was too strong for $3. So I haggled so that everyone can have oppotunity to buy 2. But I didn't consider 2-3 player games. It was a must-buy almost every time. Next, I tried Potion costs, removing cost regulation. Too swingy. Someone always cried, "Hey, where is my Province?" when I gained Colony.
Junking was another problem. Some people hated. I thought that was not so big matter. Giving Coppers gaining Silvers isn't so strong. Is this stronger than Marauder? Anyway, I removed Attack type. "May" weakened it a little bit, but still it was fun.
