I think if there's any trend to what Bloom has done so far, it's restocking the farm system with mid- to high-level prospects. As fun as it was watching Dombrowski wheeling and dealing, my recollection of his time here was that he threw too many prospects at other teams to get deals done, which hurt the team in the long run.
Here's a pretty good list of his trade history with Boston. He'd often throw in 2-4 prospects to get high-level players - helps the team in the short term, but by 2020 we've got a pretty barren farm system because of it, and we're forced to sell off valuable players because there's no low-cost help on the horizon.
Bloom seems to be doing the opposite right now - acquiring prospects, restocking the farm system, drafting interesting pieces, and augmenting the core with low-cost, high-upside players. It's the beginning of the type of cyclical team-building that the Dodgers and Rays are so good at. In another 2-3 years, we can begin dealing from a position of strength again - but I don't think we're ever going to see Bloom playing Dealin' Dave unless the return is incredibly enticing (Scherzer + Turner, etc.).
