I want to build a Cheap fun to play draft cube.

how would you go about building such a thing?

What deck building rules and restrictions would you apply?

i have never made a cube before.

Perhaps we could call this a chance cube draft format?

As someone who plays a lot of MtG Cube, this is something I've thought about as well. Seems like it could be fun, if done right.

I have a set that is 2 of every card other than legendaries. You could not include expensive rares like vibroknife and Holdout for example. We drafted from 10 characters with 8 people so you pick one and pass. 2 sets of 5 one each way. We eliminated hero villain requirements just because it made for fun groupings. Then we drafted packs that were random from the non-character rares, uncommons, and commons. I think it was 4 sets of 15 and we alternated directions again. I think next time we will include more upgrades, so maybe the pack is 6 rares and 10 (un)commons. We kept color restrictions since our card pool was large enough to allow it. I also have 3 of every battlefield in the set so everyone just picked the battlefield they wanted. We also allowed for elite characters if you were lucky enough to get 2 of them. The harder card to figure out was training. I think I’m just going to remove it in the future.

You could run all kinds of things from this like just certain expansions, all hero or all villain, only single color characters. You just need to go through the cards before hand and take out what you don’t need.

I’ve seen the same thing but singles of every card and no starter cards, no legendaries. Adding starters does make it more expensive. The less cards you have it limits the different themes you can play or how many people it will support.
