Waowa, the Transcyptic

Flying
Whenever Waowa the Transcriber enters the battlefield, put a subtext counter on target card. (It has "whenever this is the target of a spell, add any arrangement or rearrangement of some or all of the words of its flavor text to its text.")
"Shroud in words, keep up with clues, turn from end to the beginning of your spell brews — This, at last, is a way to create a link to a way of life lost."
