Talk:Gargantua Dragon, "Return Mode"/@comment-38846246-20190927190044

I have a question about this card. It says that you add a Deity Dragon Tribe Monster, THEN if it entered by G-Evo, you add another. My question is, what happens if no Deity Dragon Tribe Monsters were dropped? Does the effect just do nothing?

I'm asking because the Then implies the first effect has to resolve first and you have to add something to hand.
