When this card is on the field and you have monsters between Levels 7-12 in your Graveyard, you can use some copies of "Galaxy Queen's Light" to gain easier access to any Xyz Monster between Ranks 7-12 by using the correct monsters.
When this card is on the field and you control at least two other monsters, you can use "Level Lifter" to change the level of the other two monsters to match, then use this card's effect to match the level of the discarded monster to have three monsters of the same level for Xyz Summons.
This card can be Summoned at any time you receive battle damage, which means you can ram your monster into an opposing monster that has a higher ATK or DEF and have this card make a surprisingly quick appearance.
If you Set "Begone, Knave!" face-down, you can Special Summon "Tragoedia" from your hand when you take battle damage. When you do, activate the Set "Begone, Knave!" to return the attacking monster back to you opponent's hand for a possible direct attack.
