Sandstorm Mirage

When Sandstorm Mirage enters the battlefield
flip all creatures you control face down (you may shuffle their placement on the battlefield). Face
down creatures you control are 0/4 Mirages. If a
face down Mirage you control blocks and isn't destroyed you may flip that creature face up and
treat it as though it just entered the battlefield
from your hand. If a Mirage would be destroyed
send that face down creature to the graveyard
