Those stats look great - who wouldn't want five
power and two relevant abilities for that cost?
But since it's dependent on other cards to get
those bonuses, and your opponent is probably
going to be doing everything they can to prevent
you from getting them, I wouldn't think relying
on it is a great idea. The Behemoth may have a
place in some deck, though, especially if you
can use permanents that aren't creatures to
power it up.
