Standard Showdown booster prizes

With all the announcements from WotC about Standard Showdown boosters, the hype is real. Pull mythics and masterpieces from FREE?! 3 card boosters? Sweet! How do you get them?
Well, it's recommended to distribute UP TO 10 per event. But we have to realize that this is designed for game stores with 30-200 participants on a Saturday in mind. So when we are 6 guys on a Saturday, whats up there? For this reason we designed a slightly tuned down version of the distribution of these Showdown Boosters.

Where are they awarded?
- 3x @ Saturday 26 November's event
- 5x @ Saturday 26 November's event to celebrate a succesful Kaladesh League
- 3x @ the Boardgame Convention's Casual Challenge events (3)
- 3x @ Saturday 3 December's event
- 3x @ Saturday 10 December's event

How are they distributed among the participants?
At each of the events (except PotY) 3 of the below elements are selected at Random!
1 - Undefeated player
2 - Most losses
3 - Least victories
4 - Random player
5 - Losing the last round after being undefeated
6 - Winning the last round after all losses
7 - Random returning player from previous week
8 - Player who brought a new player in
9 - New player (first month playing at organized events)
10 - Most spend at the store (non-drink/food)
- Using Random.org
