I think it's an interesting kingdom because you don't buy Rebuild here.
That's kind of the thing about Rebuild. It's not that it makes 80% of boards into Rebuild-only boards (that hasn't been the case for
years). It's that it is either basically the only important card on the board, a card that basically has you skip building altogether, or it is a nonfactor. There's no sprinkling in Rebuild into the middle of a normal game, and unlike other hugely powerful cards like Governor, there's no board interaction or meaningful build decisions or what have you in a game where it actually is the most important card.
