This card can be searched by "Shining Angel", then flipped face-down for his effect with "Book of Moon".
Next to "Worm Zero" this card is potentially the most powerful of all "Worm" monsters. (There's a reason why it's called "Worm Victory"). Its effect to wipe out all opposing monsters is useful and it can raise its ATK to immense levels.
Use "Worm Call" to set this card immediately. Then you can Normal Summon "Worm Barses" to use it's effect right away.
If this card is in your Graveyard, you can use "The Shallow Grave" to set this card and then, use the "Book of Taiyou" to use his flip effect.
Activate "Book of Eclipse" on your opponent's turn, and flip "Worm Victory" on your turn to destroy all your opponent's monsters and protect your non-worm monsters from the destruction effect.
If the card "Acid Trap Hole" is played on this card, the FLIP effect of this card activates while this monster is returned to face-down. This could act like a nasty little "Dark Hole" for an opponent that is not expecting it. Especially if they have to later attack it to get rid of it. Because "Acid Trap Hole" is a Trap Card, you can use it whenever you wish. Including during your opponent's End phase or Battle Phase.
