Forum:Anti-aircraft flower otk

Okay so I am wondering if this OTK would work because I am unsure of the effect of DNA surgery. So it goes like this summon Anti aircraft flower and black ptera to the field and activate ultimate offering and DNA surgery to change all monsters to insect type. Then use the effect of anti aircraft flower to tribute black ptera and inflict 800 points of damage and then black ptera returns to the hand because of its effect and then summon with ultimate offering and continue this until your opponents life points are lower then yours and finish by tributing both black ptera and anti aircraft flower. So is this OTK possible?
