I really don't like the bishop/smuggler opening here. What catches my eye in this kingdom is the margrave/bank combination, either within some drawing engine or just as a draw+treasure deck. Opening with the bishop just makes that deck easier for an opponent. You're going to want a margrave yourself eventually so that means at least three terminals in your deck, creating an excessive need for bazaars. The smuggler could be useful or a complete washout, depending how the decks are built, so it makes sense to wait a few turns before buying one.
Let's go through a list of other general reasons not to start smuggler/bishop
- the risk of terminal collision isn't going to go away since the bishop is trashing cards and keeping the deck small
- smugglers might gain you more terminals that will clash even more
- you are unlikely to get a vital 5 coin hand
- the collision draw will be really bad for spending with the bishop only providing 1 coin
