2 separate requests...
In this discussion I brought up the possibility of only using 1 of your buys with a 4/3 opening. Most likely it is never a good idea, but I thought of two possibilities where it might be a slight benefit over taking an extra Silver:
BM + Treasure Maps (Less cards in deck = better chance for Treasure Maps to collide. Also might be hard to buy second Treasure Map).
BP + Trader (You plan to get 6 Silver from Estates; you don't want more than that because Golds will be better).
I'm sure both are pretty weak strategies, but I'm wondering if each strategy is better by opening X/Silver or X/nothing. Could someone add that to a BM simulator? I haven't used the simulator before. Thanks!
