This card is useful with "Honest" or "Waboku", since the battle still occurs.
Combo this card with "Desperate Tag" to take no damage, banish one of your opponent's monsters and Special Summon another Level 4 monster (including another "D.D. Warrior Lady" for a repeat combo).
This card is good against many popular cards that either can't be destroyed or benefit from being sent to the Graveyard (such as "El Shaddoll Winda"), and even though "D.D. Warrior Lady" isn't very popular, it is a 1 card answer to these cards.
