Obviously each game is unique, but in general what sort of game plan do you choose when playing against Shops? I've been trying to prioritize killing Threats, and destroying lock pieces less frequently, the idea being that they run out of threats while I have more card selection. This has not been working out for me in my limited sample, so I'm wondering how other people approach the matchup.
The thing is, they don't run out of threats. Either they draw a threat or they draw another lock piece while you spend your whole turn casting a Preordain. I think the opposite approach, going after their lock pieces, is usually a more strategically sound strategy because you'll have a few turns to chain your cantrips together and land a Mentor which will usually win you the game. That said, I don't think it's that black and white and a lot depends on the board state and what you have in hand.
