"Interplanetary Invader "A"" is a good card to use with this as not only you'll gain control of the monster who attacked it but you have higher odds of pulling out a strong reptile monster due to its 0 ATK.
An even better monster to exploit is "Reptilianne Naga". Not only can you reduce an opponent's monster to 0 ATK via Naga's battle, but since Naga also has 0 ATK, you can use this card to Special Summon a large Reptile monster from your Deck. Naga's End Phase effect, which forces it into ATK mode, also synergizes perfectly with this card.
Since you will often be using her to suicide into monsters to drop their ATK, Reptilianne Gorgon works very well with this card, too.
