Using this in a "Cyber Eltanin" Deck is a good combo. You can send LIGHTMachine-Type Monsters that are useful in the Graveyard and recover a card such as "Honest".
This card works well in a "Lightsworn" Deck. Simply use at the end of a turn to return 1 or 2 "Judgment Dragons" that have been sent from the Deck to the Graveyard by the effects of the "Lightsworn" monsters.
In a "Fabled" Deck that utilizes "Dark World" monsters, this card can both swarm the field and reload your hand with "Fabled" monsters at the same time.
If you discard "Fabled Krus" with this effect, you will be able to return "Krus" to hand (for future discarding) and use its effect to Special Summon 1 Level 4 or lower "Fabled" monster from your Graveyard.
This card works well in an "Ojama" Deck, especially if "Ojamagic" is discarded.
Set "Dragon Laser". Activate this card and discard a "Trigon", bring back to your hand a "Delta Tri" and activate its effect by destroying one monster in battle to equip it with the "Trigon" sent to the Graveyard and activate the "Dragon Laser" to destroy all opponent's monsters.
If your opponent activates "Monster Reborn" to target one of your LIGHT monsters, activate "Beckoning Light" to get that target. Your opponent will not Special Summon the target and will also not be able to activate "Pot of Duality" because "Monster Reborn" was never negated, thus being recognized as an attempt to Special Summon an monster.
