Target artifact or creature you control gains hexproof and indestructible until end of turn. If it's a creature, put a +1/+1 counter on it. (It can't be the target of spells or abilities your opponents control. Damage and effects that say "destroy" don't destroy it.)
Deflector shields use intense graviton fields to create a "solid" surface from nothing at all.
