Julia, Empress of Somnia

Hexproof, Lifelink
At the beginning of each upkeep, each opponent exiles the top two cards of their library face
down. For as long as they remain exiled, you may
cast spells exiled this way, and you may use mana
as though it were mana of any colour to do so.
Aftergloom — At the beginning of each end step,
if a creature died this turn, create a 1/1 white
soldier creature token with vigilance.
