I like the idea of playing with no banlist. I think it will be hilarious.
I was thinking to start off with a small banlist made of things that are obviously broken, like Ragnarok's Fluent Mind and Taramir's Furnace Tender. (Edit: I misread Fluent Mind. It seems fine.) There's a good argument for starting with no banlist, but I think some of these cards are pretty obviously format-breaking and you might as well nip them in the bud. I dunno. We'll see how it turns out.
Also, can you run a forum tournament for this? Because if you aren't too busy finishing up fool's gold, that would be cool.
That is pretty much what I was intending. I plan to get a subforum for NGA Constructed within the Constructed forum, then hold semi-regular tournaments. The prize could be a custom title, an Invitational-style card design, or both.
Since this is 100% digital we could always just edit cards instead of banning. Banning could just be a temporary measure for cards that are awaiting redesign.
Speaking from a competitive point of view, I'm against the idea of "patching" the format. It's a valid choice, one that a lot of serious games like Starcraft II use, but I think it's more interesting to leave powerful designs in place and either ban them if they're too oppressive or work around them if they have answers. There are a lot of things in Solphos that I kind of regret, but I'm not going back to change them. I know the metagame will adapt to accommodate their presence.
Should we have a specific order for the blocks in the NGA format, so we can create different "standard" environments?
I think it's better to have one unified format than a whole bunch of disparate formats. Even if the format ends up really big, you can easily create casual decks or theme decks if you want.
