Delita Heiral

Focus — When you cast this spell, roll a six-sided die. It
enters with a number of shield counters equal to the
result. (If it would be dealt damage or destroyed, remove
a shield counter from it instead.)

Steel — Other legendary creatures you control with power
less than or equal to the number of counters on Delita have
protection from instant and sorceries.
