Elturel Survivors

Trample, myriad
As long as Elturel Survivors is attacking, it gets
+X/+0, where X is the number of lands
defending player controls.
Except Rionya, noone survived the attack on Elturel.
But her will and power bends the lava and from time
to time, shadows resembling her precious friends
emerge from Valakut, only to disappear shortly after.
