One ruling from Wizards of the Coast
- 22 September 2011Consider only the number of +1/+1 counters on Primordial Hydra when determining if it has trample, not its power and toughness. For example, a Primordial Hydra with six +1/+1 counters on it that's been the target of Titanic Growth (giving it +4/+4) would not have trample.
