Notes & Combos
You can replace the hand traps with anything else you got but droplet comes in really useful sometimes, so keep that in mind. The non-marincess extra deck cards can be replaced except for splash mage.
As of writing this the guide on the site for how to play is outdated, regardless you can learn to play the deck from it. It has most of the combo lines, so if you're new follow that, but keep in mind that in the end you usually want to summon the new card called Marincess Aqua Argonaut instead of Bubble Reef.
Another thing to keep in mind is that the new Marincess Springirl card enables 2 card combos as well, so you can make a completely unaffected Argonaut.
