So the general rule with reactions is that you may react them in between sentences of other cards, but not mid-sentence? Or what? I know this sounds weird, but it seems to be the case. And I can't think of any counterexamples to that.
Reactions react to certain triggers; the sentences used to describe the actions that activate these triggers are irrelevant. In Market Square's case, the trigger is "the act of trashing."
The key to understanding this is to think of the "trashing" trigger as a single event that involves many cards. Here's how it breaks down, in Count's case:
- You play Count.
- You choose the option "topdeck a card" and topdeck a Copper.
- You choose the option "trash all the cards in your hand".
- Your hands consists of Copper, Copper, Market Square. You trash these 3 cards.
- The "trashing" trigger is activated.
- Market Square is not in your hand (it's in the Trash), so you can't reveal it.
Let's think of another example. Your hand consists of Count, Market Square,
Rats, Copper, Copper. Here's how it breaks down:
- You play Count.
- You choose the option "topdeck a card" and
topdeck the Market Square.
- You choose the option "trash all the cards in your hand".
- Your hands consists of Copper, Copper, Rats. You trash these 3 cards.
- The "trashing" trigger is activated.
- Rats reacts to the trigger. You draw a card... which happens to be the Market Square you topdecked.
- Market Square also reacts to the trigger. Since it is in your hand, you can reveal it and gain a Gold
(Can someone please confirm that this second example is correct?)
