What more substantial do you want?
Qualifying regionals that pay out 5K to the top 4, funneling to some special worlds event with 10K in prizes to the top 8, and then a cruise?
I anticipate counters, play mat, t-shirt, accesories, that you'll have to pay for to have for the events (at a discount). Then there will be the occasional larger things at large-ish conventions, like Gencon, which will have some trophies and perhaps the reward to create your own card like in CoC / AGoT.
UFS is pretty much the same thing (or it will be pretty much the same thing) as the LCGs, except it has some local play / tournament exclusive promotional cards (only obtainable through playing in local events, or attending larger events), and then Play Mats, counters, and the design a card AKA THE GREATEST PRIZE IN GAMING (your likeness and photo on a card, named whatever your name is, with your creative design, which you will own all 500 copies of, to distribute as you see fit, not to be released in any other format, ever).
If you've suggestions, feel free to post them here!
