Whyrl did this awesome image way way way in the beginning.  This is probably one of the first MND images that Whyrl did and it just looks great.  This was one of the first cards templated for Tainted Glimpses - after all, a Xyx is an Arderial staple and almost every expansion produced since Base has had a Xyx.  This Xyx combines the dice throws of the previous Xyxs with the discard mechanic of Arderial.  It has immunity to discard in and of itself though, and can't be discarded while it still has energy.  This is a powerful card indeed, and will fit in well with most Arderial decks.  It definitely fits into the Xyx creature type decks!
