1. By the search function of yugiohex2006, I cannot find a suitable card for this.
2. No. I have said to you before.When you have already a gemini monster on your field and you have not conducted your normal summon, you can announce that you are conducting your second summon and it gains its effects. Also,no tributes are needed for second summon.
