Yugioh Question: Can you use Glad Beast Darius effect to get back Herklinkos or Gyzarus?

Question

Assuming that you have summoned Herk and Gyz through proper contact fusion before

Answer 1

Darius can bring back any glad beast but they don't get there affect because of darius, and if you attack with darius and whatever you bring out, you will lose the monster you brought out because they tag out at the same time and since darius leaves the field that monster has to go back in the deck, so attack only with the monster you bring out and not darius so you can tag it out. Also a neat trick is if you run books (which you should) when you special darius and bring out another glad beast book darius and the monster you brought out gets its affect because darius is no longer on the field, it is amazing with gyzarus, i laugh so hard when I do it to people and they are like WTF!
