Luminous Dragon Ritual

Regarding "Must be Ritual Summoned with 'Photon Ritual Art'. You must also Tribute monsters from your hand or field whose total Levels equal 4 or more": This is the effect processing when this card is activated. (This effect does not target.) During resolution, you perform the process of "Tributing monsters from your hand or field whose total Levels equal 4". After that, you perform the process of "Ritual Summon 1 'Paladin of Photon Dragon' from your hand". The process of Tributing and the process of Ritual Summoning do not occur simultaneously. You can also select monsters in face-down Defense Position in your Monster Zone as monsters to Tribute.

Regarding "You can banish this card from your Graveyard during your Main Phase; banish monsters from your Graveyard whose total Levels equal 4, then Special Summon 1 'Paladin of Photon Dragon' from your hand as a Ritual Summon": * This is an effect that activates in the Graveyard and creates a Chain Link. (It does not target. When activating this effect, you banish this card itself from the Graveyard as a cost.) * At the time of resolution, you perform the action of "banish monsters from your Graveyard whose total Levels equal 4," and if you successfully banish them, you perform the action of "Special Summon 1 'Paladin of Photon Dragon' from your hand as a Ritual Summon." * The action of banishing and the action of Special Summoning are treated as occurring simultaneously.
