Tyrant of the Unreal

Nightmare - Discard a card. (This creature enters the battlefield with a dream counter on it. You may
pay its nightmare cost at any time to remove a dream counter from it. Creatures with dream counters on them are enchantments and lose all other card types.)
Discard a card: Put a dream counter on target creature you control.
Whenever a dream counter is removed from a permanent you control, draw a card.
