Grasp Of Thorns

When this enchantment enters the battlefield, tap 3 creatures an opponent controls, and place three Grasp counters on each. If a creature with Grasp counters would attack or block, remove a Grasp counter and that creature gets -2/-2 until there are no longer grasp counters on the creature.
