Morpheus, Dream Demon

Indestructible, Flying
If all other creatures are not tapped, Morpheus is not a creature and loses this ability:
{1}: Exchange an ability between two creatures, or change one creature type.
{1}: Tap all other creatures you control.
When you draw a card, distribute two dream counters among two creatures. Creatures with dream counters don't untap. Remove a counter at your upkeep, or two when an opponent casts a spell
