Emergent Haunting
Enchantment, {1}{U}
Oracle Text
At the beginning of your end step, if you haven't cast a spell from your hand this turn and this enchantment isn't a creature, it becomes a 3/3 Spirit creature with flying in addition to its other types.
{2}{U}: Surveil 1. (Look at the top card of your library. You may put it into your graveyard.)
