Balance is still the best skill for Barnacle deck. Decklist (6 monsters, 6 spells, 8 traps)
3x Drill Barnacle
3x Raging Flame Sprite
3x The Fang of Critias
3x Power of the Guardian
3x Tyrant Wing
3x Jar of Greed
2x Legacy of Yata Garasu
You can run 3x Good Goblin Housekeeping + 2x Jar of Greed if you don't want to spend your SR Ticket on Legacy of Yata Garasu
actually my deck is
3x drill barnacle
3x Power of the Guardians
3x Banishment of the Darklords
3x Darklord Ixchel
3x fang of Critias
3x Tyrant wing
2x Cup of Ace
cup of ace cause if heads you get +1, if tails you break Kalins "no hand combo" by giving him 2 cards, you don't need to draw 2 anyways. You don't have banishment and 3 ixchel? well hahahahaha
btw here's my results
