Bandit and Conductor interaction with the Goldenizer

So I just found out that trincket’s Goldenizer can be consumed by Bandit or Conductor on the same turn it is added to your hand, even if you had other blood gems on the previous turn.

Like I get it’s a spell, but my logical brain was like, there is no way they would design the game like that.

It would make more sense if the Goldenizer is added to your hand after the effect takes place.
