I suspect this card will mostly be seen as a
highly variant Tarmogoyf (low-cost, long-game or
high-impact creature). That's a good use for it,
especially since lands tend to get destroyed
less frequently than graveyards get tampered
with in the modern era. Beyond that, most land
creatures don't need too much help, and in
situations where they could use a power and
toughness boost the Advocate itself is probably
going to be just as vulnerable to the opponent.
I'd still consider it in casual settings for the
uniqueness, not to mention the overkill factor
when combined with Liege of the Tangle!
