I am jealous, mine are still sitting in the queue. Last year it took almost a month.
Which day were you able to release the holds?

For impulse, I will guess some of the smaller ones since we tend to take more risks with those. Canvas and Radlands perhaps? (Both of those are great btw) And maybe Splendor Duel, guessing you already had regular Splendor so you were hesitant about getting Duel too.
