Yay Insect DECK!
I perfectly master those.
First of all you need 3 doom dozers cause it's easy to summon and it rocks! You will aslo need 3 pinch hoppers, it's one of the must important cards on insect decks, read my article and you'll see why. try adding howling insect too, it will help you to get pinch hopper.
Insect decks summon strong monsters easly, so you don't need cards like DNA transplant insect barrier or pircle fairy, remove those.
