Ur-Shyr, Heart of Darkness

Shroud, fear
At the beginning of each upkeep, you may
choose a permanent card a player owns in exile.
Until the end of turn, you may cast that spell as
though it had flash, and you may pay an amount
of life equal to its converted mana cost to cast it.
If a creature card is played this way, it gains fear.
"Don't fear the dark. Dread what lurks inside."
