What cards could change competition when Chaos Impact launches on Friday? Leon's got a pretty big list of his personal picks, ranging from the strongest Secret Rares to some sleeper-hit commons that are flying under the radar.

Hit today's featured video and see which cards caught Leon's eye, and which could have serious potential.
