Use "DNA Surgery" to disable the first attack of all monsters your opponent Summons. Unfortunately, it will also affect your monsters since its effect will be identical to "Vengeful Bog Spirit".
However, in a non-Dragon deck, you can use "Buster Dragon" to make all your opponent's monsters Dragon-Type, then using this card's effect by declaring Dragon-Type will make only your opponent affected by this card.
Use "Non-Spellcasting Area" to allow your Normal and Gemini monsters to attack on the turn they are summoned.
This card is great against all Type-oriented Decks.
