Draw as out your combo as fast as possible to win the duel before your opponent reduces your LP to 0.
Set Crystal Seer to stall without losing card advantage. Crystal Seer can take an opponent's attack, and when flipped face-up, she adds a card from the top of your deck to hand.
Only use Into the Void if you are sure you can finish the duel or if you are certain you will lose the next turn. Otherwise, you will discard all your cards during the end phase, which will be impossible to recover from. Another time you can use Into the Void is when you already have Ocean Dragon Lord - Neo-Daedalus on the field, and you are trying to draw A Legendary Ocean.
Even if they activate E-con, Daedalus' effect has already been activated, so even though your opponent won't be able to attack, you still won't be able to defend next turn, unless your hand is hiding strong defense that you didn't set
I mean, yes it's a pretty bad deck, but not because it's weak to E-con. It's bad because you can easily brick and it has low consistency and it's not as fast as most meta decks. That said, I don't think many people who'd want to play this deck are looking for a top tier deck, just a viable way to play Levia Dragon with Ocean Dragon Lord just for fun, if they happen to like the card.
They should remove Skills from PVP imo. Or at least competitive PVP, like KC Cup. Or nerf A LOT Mind Scan. I'm ok with Destiny Draw... it's really predictable when you play against Yami Yugi. I'm ok with it... But I'd like to have it !! 6 month in this game and it has never dropped yet !
for everyone calling it cancer, it doesn't really matter because everyone is just gonna econ take before you use the effect LIKE EVERY DECK DOES so relax
