Melvin, the Meddler

{x}{r}{r},{t}: Choose an opponent's enchantment.
That enchantment's text is replaced with the text
of another enchantment in play or in any
graveyard. This effect lasts indefinitely, and can
only be used once. Here, X is equal to this card's initial CMC.
Melvin delights in chaos, pulling the strings until reality unravels itself.
