Marincess is seen as somewhat competetive versus the dominant Snake-Eyes due to the sheer amount of non-engine they can run. Therefore, I thought it was a good idea to give you guys an updated decklist from the one shown in the linked video (where we go over the 1 card combos this deck can perform).
In case you have questions, feel free to drop them in the comment section of the linked video.
The side deck is full of cheap(er) alternatives in Master Duel, which you can use as part of the non-engine.
