Jump In packs
There are too many unplayable packs in the Jump In event. I love the format and would like to play it more frequently, but the lack of basic curation of the packs is making it difficult to love.
Transience and Recruits have been especially bad. Black Market Connections is very close to unplayable with 95% of the packs, and Recruits includes a sorcery with blue kicker, but does not force select white/blue packs to go with.
Many of the packs also include cards that synergize with cards not included in the packs. Like War-Trained Slasher without a Battle to attack.
My suggestion to fixing these problems: Midweek Magic where players have to construct a Jump In style packs and then you just copy what ever people liked to play the most. Simple and cheap!
