Animate Everything

All opponents must choose either Lands, Artifacts or Enchantments, however all 3 apply to you. The chosen cards enter with a number of +1/+1 counters on it equal to its mana cost, minimum one. On each players turn all cards of the chosen type become creatures in addition to their other types (If
it's an Aura or attached equipment it only applies +X/+X to the creature)
