Over the years, Marincess has gone from a decent competitive option to a potential meta contender in the TCG. So one could say that they've leapt the Dragon Gate. What does that mean? Lemme explain.
In Chinese mythology, there is a gate called Dragon Gate on top of a waterfall in the Yellow River. Many carp try to swim upstream and leap over the waterfall, but few are strong or brave enough to do this. If a carp manages to jump over the waterfall and reach the Dragon Gate, they will be transformed into a powerful dragon. This is so famous in China that "trying to leap Dragon Gate" means suddenly improving your social status.
In light of that and how Marincess went from good to great, this deck is named "Marincess Dragon Carp."
As for this deck, it does better going first, but thanks to the 12 hand traps this deck plays, it can be decent if it has to go second. Your strategy is to set up as many disruptions as you can, and this deck can end on a board consisting of Aqua Argonaut summoned with Marincess Crystal Heart, Toadally Awesome, Battle Ocean, and a Marincess Wave or two.
