Ileya the Silent

Deathtouch
Whenever Ileya attacks a player she phases out.
(While she's phased out, she's treated as though she
doesn't exist. She phases in before you untap during
your untap step.)
{u}{b}: If Ileya is phased out she phases in and
deals damage equal to her power to the last
player she attacked or a creature or planeswalker
they control.
