Kudzu, the Invasive

Hexproof
If Kudzu, the Invasive would deal damage to a
creature, instead put that many Kudzu counters
on that creature.
Creatures with Kudzu counters lose all abilities,
become green Plant creatures with base power
and toughness 0/1, and gain "{t}, Tap a Goat
creature you control: remove a Kudzu counter
from this creature."
