Ayristasi, Naya Wanderer

First Strike, Vigilance
Domain — Ayristasi's toughness is equal to the
number of basic lands you control. If a basic land
comes into play under your control, Ayristasi
fights target creature an opponent controls.(Each
deals damage equal to its power to the other.)
"She wanderers the savannah mountains, vigilant to
its defense and beholden to no one."
