This card is useful for allowing one's "U.A." monsters to temporarily eliminate difficult monsters, as well as rid Xyz Monsters of their Xyz Materials, allowing room for other "U.A." monsters to attack directly.
As a result, this card can serve to deter the opponent from attacking "U.A." monsters.
This card can be discarded for the effect of "U.A. Perfect Ace", allowing its last effect to be used immediately.
If this card is on the field, the effect of "U.A. Dreadnought Dunker" can be used to destroy it so that its last effect can be used.
Since "Paleozoic" Trap Monsters can be used in a "U.A." Deck to serve as Tributes, their cards can enable this card's last effect in a variety of ways.
