I wanted to share a new format my friends and I have been playing that we think is really fun.
The format is as follows: You start by each buying a prerelease kit, and you keep an inventory of all the cards that you open from it. These cards are now what's in your "pseudo collection." Then you all agree to a weekly budget that you spend on packs and the cards you open from such packs are added to your pseudo collection (for my group it's 2 packs per week). Then you basically craft whatever legal deck you can make from cards in your pseudo collection. You are also not allowed to buy singles for your pseudo collection, you can only use cards from packs that you open. The idea is that instead of everyone constantly having an optimized deck with 4 of the best card every time, you play with exactly what you get like a draft, but your collection also slowly grows. Also you can have any number of basic lands. Of course this format relies on the honor system and having a good group of friends, but it's genuinely a lot of fun and you should try it if you have not already.
