Enchant creature you control
When Starlit Mantle enters the battlefield, enchanted creature gains hexproof until end of turn. (It can't be the target of spells or abilities your opponents control.)
Enchanted creature gets +1/+1.
If Starlit Mantle leaves the battlefield before its enters-the-battlefield triggered ability resolves, the creature it last enchanted before it left gains hexproof until end of turn.
