Flesh & Blood: Armory Gem 5 Pack Chaos Draft Store Championship!

Anytime there is a 5th occurrence of a Thursday in a single month, it will trigger some form of a hybrid store championship!
Each participant will be given 2 GEM packs for this event. They may be used as part of their drafting. As for the rest of the drafting, this is the fun part! Players will choose and purchase 5 packs from shop stock. Purchased packs go into a "blind pool" a.k.a. bucket of some sort. Once all players have made their purchases, players--one at a time will randomly choose 3 packs out of the shared pot to build their decks. Players may bring an extra hero, as a back up, should they not get one in drafting. 3 Pack Crack rules apply.
The remaining packs that are in the prize bucket are used for prize payout in addition to additional GEM packs. First place will get 3 Gem Packs, and choose 2 packs from remaining shared stock--of their choosing; 2nd place 2 Gem Packs, and 1 pack from remaining shared stock of their choosing. 3rd Place 1 additional GEM pack, and 1 pack from remaining shared stock--chosen at random. This process continues on prize payout (minus the additional GEM packs) until all shared surplus packs have been claimed.
Participation and Placement points are available for this event. Participation points of 10; placement points: 1st place: 8; 2nd place: 5; 3rd place: 3.
