This card can be used to Ritual Summon any Cyberse Ritual Monster. You must also Tribute "@Ignister" monsters from your hand or field whose total Levels equal or exceed the Level of the Ritual Monster you Ritual Summon. If you control an "@Ignister" monster when this effect is activated, you can also use "@Ignister" monster(s) in your GY, by banishing them.
