Lorwyn Eclipsed draft guide: Why Mirrorform is the best card in the new MTG set

I was two matches into the tournament and feeling pretty good. My green-black elf deck was doing exactly what I wanted: make lots of elves quickly and then throw them underfoot for value just as fast. My army was growing steadily, led by a hulking Champions of the Perfect, a 6/6 elf warrior that was also drawing me extra cards each turn. Victory seemed certain. Then, my opponent played Mirrorform and killed me in one fell swoop.
