This is based off of the formats from Netrunner 1.1.1 and 1.1.1.1.
The basic idea is that you pick a whole set (the homeplane), then a booster from another set (15 cards), then a single card. The format's goals are to allow you to play with individual high powered cards but with overall lower powered decks. Since an individual deck's usable cardpool is always a fixed size (even if of your choice) you must pick sub-standard cards to play next to your high powered cards.
Edit: It's easier if it's just 1 core set + 1 expansion set + 1 card.
Anyways, an example:
Let's say want to play Tron, because the Tron lands are powerful especially among threats like Wurmcoil Engine, Steel Hellkite, and Myr Battlesphere. I pick the set Scars of Mirrodin. I pick 15 cards from Ninth Edition: Yavimaya's Coast, Urza's Tower, Urza's Power Plant, Urza's Mine, Naturalize, Sleight of Hand, Mana Leak, Defense Grid, Dragon's Tooth, Icy Manipulator, Fellwar Stone, Quicksand, Counsel of the Soratami, Remove Soul, Reclaim. I pick the single of Ancient Stirrings. All cards chosen can be used to make my deck.

I then construct the following:
4 Urza's Power Plant
4 Urza's Mine
1 Quicksand
4 Yavimaya's Coast
3 Forest
3 Island
4 Fellwar Stone
4 Ancient Stirrings
4 Sleight of Hand
2 Mana Leak
2 Remove Soul
2 Icy Manipulator
3 Wurmcoil Engine
3 Steel Hellkite
3 Myr Battlesphere
4 Counsel of the Soratami
2 Reclaim
3 Naturalize
4 Turn Aside
3 Nihil Spellbomb
3 Dragon's Tooth
2 Defense Grid
I'm arbitrarily picking a Modern archetype. The example, while unoptimized, demonstrates a potential deck.
Thoughts?
