Field of Swords

Whenever a creature dies, exile it instead.
If its power was greater than its toughness its
owner creates an equipment token named
sword with "equipped creature gets +1/+0"
and "equip {1}".
If its toughness was greater than its power its
owner creates an equipment token named
shield with "equipped creature gets +0/+1"
and "equip {1}".
If its power and toughness was equal, the
owner creates both.
