Skarmory

Flying.
Skarmory can't have -1/-1 counters placed on it.
Whenever Skarmory is dealt damage for the first time each turn, prevent that damage.
{2}, {t}: Return target creature with toughness less than Skarmory's power to its owner's hand.
{2}{c}{c}, {t}: Monstrosity 1.
When Skarmory becomes monstrous, target player creates a green and white enchantment token named Spikes with "Creatures you control without flying get -0/-1."
