Here is my Kcdvs gemini deck... Please fixed

Nothing to fix. Using a gemini card in a specific deck = good. Using a deck based on Gemini monsters = bad. It is really that simple. The gemini monsters have no synergy with each other except for summoning Raptinus which isn't a good enough reason to use them together. So bad deck-type is bad. =(
