Then this costs three and then brings back any dork with a cheaper cost at five or fewer or Spacecraft too and then makes you a ramping Lander too, but you need to sacrifice something of the artifact (might I suggest tokens like Treasures) or dork (ditto like Robots or Zombies) persuasion
While this isn't an exact science (since expensive reprints will limit the price of new cards, which might be hurting the Bant deck a bit, since it has the highest-value reprints), this system works pretty well in general
Even returning Urzas Saga can help you close the game when applicable
