Kayt, Eldest Daughter

Celebration — At the start of your end step, if
two or more nonland permanents entered the
battlefield under your control this turn, Kayt,
Eldest Daughter deals damage equal to her power
to target creature an opponent controls. If a
creature is defeated this way, untap all nonland
permanents you control.
As the eldest and wisest, Kayt ensured her sisters'
celebrations went undiscovered. Her special brew
helped the guards sleep through the night.
