Rare X

You know what is nice about Rorix besides all his other, obvious, attributes? It is the fact that he is a rare. I know it sounds dumb, but it’s true. People don’t play as well against rares. They don’t expect to be facing rares. They aren’t accustomed to playing against rares, so they are more likely to play poorly when facing rares. Entire Limited articles are written sometimes as if rares barely existed. How can you account for this in your Limited playtesting?
