Ritual Summon

A Ritual Summon ( Gishiki Shōkan) is a method of Special Summoning a Ritual Monster which uses the effect of a Ritual Magic Card.

Ritual Summons usually require Releases greater than or equal to the Level of the monster being Summoned from your side of the field or your hand. These Releases are performed as part of the Ritual Magic Card's effect resolution rather than as a cost.
