I've considered it lots :) I've done quite a bit of thinking about the architectural underpinnings of draft support.

It's the second stage of three logically connected steps, each of which is a major enhancement that'd take quite a bit of work:

1. Decklists. Let people group cards from one or more Multiverse sets (optionally also cards from printed Magic sets too) into decklists. Provide some nice stats on colour balance, symbols, average CMC etc. Provide a nice view for printing proxies.

2. Draft support for drafting our custom sets with each other.

3. An online gaming table for playing our custom sets with each other. No rules enforcement, since we'll be making up crazy new rules texts all the time, but provide a space for drawing cards, dragging them onto the battlefield, tapping/untapping, making tokens etc.

1 is a necessary prerequisite for 2 and 3; 2 and 3 could kinda be done in either order, but it makes more sense to me to do 2 before 3.

Suffice to say for the moment it's something I'd definitely love to do, and I think it is actually feasible for me to do, but it'll take quite a lot of work. When you see decklists appear, you can consider us halfway there.

That all makes sense, and you've obviously thought about this more than I have. And hey, this is already a great site, so don't think you have to do it at all, or anytime soon. Just a thought for some bigger stuff to add.

But all that would be awesome. I wish I knew how to program stuff, I would offer to help.

I'm curious if maybe it's possible to collaborate with, say the people at tappedout.net or Bestiaire.org to see if there's a way to arrange some collaboration for online drafting with custom sets?
