Rules question: when you use a trash for benefit on a card that has a benefit when trashed, which benefit happens first?
Eg: your hand contains a rat, a remodel, and a watch tower. You remodel the rat into a gold and reveal the watch tower to put it on your deck. Do you get the +1 card for trashing the rat before or after gaining the gold?
Imagine if shelters was an action that read "place this shelter on a pile in the supply. It must be gained before gaining any cards beneath it." with a cost of 2.
The implication would be tremendous, although games may never end.
