Based on my wealth of experience over the last almost 3 days, I can confidently say that this card is definitely pretty good in many respects, but weak in others. On certain boards, it has a significant advantage over Bridge, but it's hampered by certain key factors, especially on unfavourable boards. It can be used as a gainer, and your second Inventor can gain you a key
. But one must not overlook the potential for megaturns, with the possibility of multiple Province gains a potential prospect on supporting boards. As a Workshop variant, it is better than the original Workshop, but unique in comparison to variants such as Ironworks and Engineer. They all have particular niches and within them their strength needs to be re-evaluated, likely to a significant extent. An inability to play more than one inventor will likely be a major factor against this card, although, depending on the kingdom, certain decks could be strengthened with the addition of one or possibly more inventors.
