It's light on details for talking about a "format". How many cards were in each packs? Did players get just one, or were many distributed to players? Were they randomly put together or seeded in some way? Was there a thought around rarity distribution like normal packs?

On the topic of fun 40 card decks, after my partner and I thoroughly (winston) draft through a bunch of packs in a set, I like to make a battle box of a few 40 card decks which are more coherent than the average limited deck.

I think people get too hung up on the formats in sanctioned tournaments. People says "magic is expensive", but that's not true! Modern decks in the metagame are expensive. You can play magic on the cheap an infinite number of ways. There's near endless opportunity for replay value in 3 packs per person!
