Usefulness may be debatable, but I'll be damned if it's not one of the best flavour texts of all time.

Simple stuff for a rare, and deadly nonetheless. You've got no shortage of big tramplers in green. Best of all, it's an instant. Imagine them letting a 1/1 through and suddenly you turn it into an 8/8. Have two of these and eight mana? Why not make it 15/15?
Properly costed; 
would've made this borderline broken, at least in green.
