Below is a partial quote from one of the owners of Asgard Games in reference to the upcoming tournament. His full post can be found
here. Hope to see a good turnout next weekend. Note the rules about proxies that I bolded.
It is a $5. With this fee you receive 10 proxies (this gives people a decent foothold into the format) After that, any additional proxies will cost $1. This allows for some of the standard players etc to break in at a significantly lower cost (Most of the people that play legacy will have duals/fetches etc, the standard players will not).
As far as the proxies go, Slips of paper in the sleeve that are print-outs are required, but make sure you cut them enough they don't slip out the top of the sleeve. This will make it easy so that everyone can read the card (Not everyone will know all of the cards by name etc.)
