The Importance of Design Space in Magic

Magic is a trading card game which we've signed up for. We're constantly making new content and you know there I like to say that your greatest strength is your greatest weakness are basically the two sides of the same coin right magic's greatest strength is it's got a lot right it's a complex system. One of the biggest problems we find with new players is when I tell you there's 25,000 pieces talking right chess has six and chess seems complicated. How do we know that the design space that we're adding is big enough to be worthwhile how do we like what's the process of evaluating when some new designer says I got this great idea?
