This is a Mermail deck that doesn't include the Firewall combo.
I included "Fishborg Launcher" and "Fishborg Archer" for Synchro plays and use Exodius to get the discarded cards back into the deck. Hand Traps were completely removed since Update 1, because of the Fishborg cards. Maybe i will include the Water Elemental Lord as soon as i can get the card.
09-25-2018 Update 3:
Main Deck: 1x "Moulinglacia the Elemental Lord" was added. 1x "Mermail Abyssdine" was added. 2x "Called by the grave" was added. 1x "Moray of greed" was removed. 1x "Dark Hole" was moved from the Side Deck into the Main Deck. 2x "Solemn Strike" added. 1x "Solemn Judgment" removed.
Side Deck: 1x "Gamaciel, the Sea Turtle Kaiju" was moved from th Main Deck into the Side Deck. "Fishborg Archer" was removed. "Mare Mare" was moved from the Main deck into the side deck. "Mermail Abyssturge" was moved from the Main Deck into the side Deck. 1 copy of "Atlantean Marksman" was moved from the Main Deck into the Side Deck. 1x "moray of greed" was moved from the main Deck into the Side Deck. 1x "Abyss-squall"added. "Mermail Abyssleed" was removed.
It is possible that i changed something else, but i have no clue what it was.
