Echosand Delver

Protection from Traps.
When Echosand Delver enters the battlefield you
may sacrifice any number of nontoken artifacts.
For each artifact sacrificed this way create a 0/1
White Elemental creature token named Decoy.
Whenever Echosand Delver would die you may sacrifice a creature named Decoy instead, when
you do put a +1/+1 counter on Echosand Delver.
