Upon entering the shopping phase, you are presented with three items. One from the Secret Shop, one item you put in your deck, and a consumable. These always appear in a random order. So what do you do if you see an item you want now, but only have enough gold for next turn? Thankfully, there’s the hold option. For a small fee you can prevent item rotation from happening, and ensure you’ll get offered the item of your desire in the next shopping phase.
Making the decision to hold or not is all about assessing the available items and the items that aren’t offered. Sure, one item that’s being offered now is very appealing. But if you hold the shop you hold all three items. If you think you should hold the shop because of an item in the Secret Shop, remember that you also won’t be offered a new item from your deck. An item which could be of even more significance as the game progresses.
