Effect
Cannot be Normal Summoned or Set. Must be Special Summoned (from your hand) while 3 or more of your LIGHT monsters are banished, and cannot be Special Summoned by other ways. Once per turn: You can target 1 of your banished LIGHT monsters and 1 face-up monster on the field; shuffle the first target into the Deck, and if you do, banish the second target. This card cannot attack during the turn you activate this effect.
"This card cannot be Normal Summoned. It can only be Special Summoned if you have 3 or more of your LIGHT monsters banished." is not treated as an effect. It is a procedure to Special Summon a Special Summon Monster. (A chain block is not created when performing a Special Summon this way.)
It cannot be Special Summoned from the Graveyard by the effect of "Monster Reborn". It can only be Special Summoned from the hand by the method described in the text.
"Once per turn, you can target 1 of your banished LIGHT monsters; return it to the Deck, and if you do, banish 1 face-up monster on the field. This card cannot attack the turn you activate this effect." is an Ignition Effect. (This effect targets 2 monsters in total: 1 of your banished LIGHT monsters and 1 face-up monster in a Monster Zone.)
The process of "target 1 of your banished LIGHT monsters and return it to the Deck" and the process of "banish 1 face-up monster on the field" are treated as occurring simultaneously.
