Magic circle against good

Magic Circle against Good, also known as Protection from Good, 10' Radius, was an abjuration spell that created a sphere of warding against mental and physical attacks from good creatures. The older version of this spell was reversible, called Protection from Evil, 10' Radius, and had identical effects on evil creatures.

Effects
This spell operated just like magic circle against evil except that it extended the area of effect for protection from good rather than protection from evil,   and it could trap a nonevil summoned creature.
