Well, now that the event is over.. I'll throw in my 2
.
First of all, as most people will agree, the event was long... Too long. It ran nearly 2 months.
Some factors contributed to this: WAR, 3 organizers, 60 participants.
As far as the event went. It was really fun. Trying to figure out what your opponent would play with what they had left. Although the marks didn't do to much in preventing decks. You could still play most any deck really, if you were willing to sacrifice the quanta from your MARK.
If I was running the event.. this is what I would do: (easiest way to give feedback lol)
Eliminate the +1 life and -2 lives for the sweeps.
Going 3-0 and not losing a life should be benefit enough. Two players, #1 3-0 and #2 3-1, would have only have a 1 life difference instead of 2. And losing 5 lives to a sweep is such an insanely high amount.
Other than that, nothing really should be changed.
*** Although, I still think it would be interesting that if you lost a MARK, you couldn't use any cards from that Element either. ***
