Fallen Ones

When Fallen Ones enters the battlefield, enchantments become Azra Demon creature in addition to their other types with power and toughness equal to its converted mana cost until
the end of turn.
Enchantments you control have haste, trample
and gain: "At the beginning of combat, if this permanent is a creature, it gains +X/+X, where
X is the number of enchantments on the battlefield."
