First of all thanks for including my pvp version of passcode to the guide.
Secondly i would like to place an quite important additional option you didn't mentioned. But before few words on my pvp version of deck.
Street Idol Clarice PvP version (based on akihito's build) - 100DP is a deck purely oriented at pvp. It's as much antideckout as possible for passcode and it allows to get strong field presence ASAP. What wasn't mentioned it's that recycle follower on field allows you to be rookie target at any case. This is why it needs to be played with Rookie debut. I strongly advice this setup (or similar) for pvp purposes and it can be done with basic Alchemist Clarice as well even though it isn't so strong. Main key for good cheap versions of pvp passcodes is to make use of free dp left and include lukif. In lowest pvp bracket it can be very hard to counter or even in some cases impossible which allows you to get some freerolls. Lukif is also highly recommended in 300 dp versions as well as grinding decks. Of course if you can allow the cost of crafting.
Crux Passcode - PvE/ 300 DP pvp is the more expensive passcode version but better one and can be improved a lot. This deck I put in is just general idea deck - aim is to exchange rookie buff for Sisters Reunion buff (4x +4/0/+4 or 3x +3/0/+3 with added possibility to get rid off lukif due to -3/-3/-3 debuff if only 1 follower is put) and Demotion (possibly +4/0/+4 but may be as low as +2/0/+2) and improve deck with d.rare crux followers oriented spells like Luthicas Ward/Dignity/The Truth Revealed/Shock/Forced Return/ Pacifism maybe Sanctuary Pillar or Totem. In addition you can use very funny but powerfull in this setup spell called Smallification and maybe Sending information if you feel lucky and adventorous (very risky option but may give buff as much as +6/0+6 for 3 followers).
Char is usually picked up from crux chars but it doesn't have to be, you may decide to pick up mighty child Helena for example, it's really up to you but you can't play Clarisse chars. This deck has possibility to improve up to around 350 DP and than you can switch your followers to 2 sizer crux followers and play so-called Crux mass deck (similar idea just 2 sizers with some twists) which you can improve further up to around 500 DP.
But... before we clap our backs till no tomorrow there is something to be said about passcode decks. It's aim is mainly to be cheap grinding deck and quick improvement for beginners. As for pvp stage there is quite number of better decks even with buffing abilities. Passcode is safe all-around choice with decent outcomes but can't be treated as Holy Grail. As i mentioned it can be used as a pit stop before achieving crux mass deck evolving itself into stronger version which is capable of doing more damage, but main goal of passcode is just to be very cheap and as effective in it's price as possible.
I don't know anything about this. Can you turn on framerate display by hitting F12 and let me know what your framerate is. If you are using a non-potato computer and have graphics drivers installed it should be 60 or higher.
It always depends according to your preference, even if it's just a general non-restrictive faction deck. There's that deck that focus mainly on buffs, others debuffs, or can be a mixture of both. For budget build deck, there's always the "Passcode Deck" where every followers in your field with same size buffs a lot at same time. There's also this "Normal Deck" featuring some mixture of both buffing and debuffing like Disappearance spell, etc. There's also the "Pure Debuff Deck" where everything is focused in burning enemy HP and/or destroying enemy followers in a single move. There's also (aside from those 3 aforementioned decks) the special type decks where focused on something else (locking enemy field, stalling, etc.). So in the end, it depends on your build, if you want your deck to be the "best". As for low budget deck, I will suggest Passcode Deck.
Answer for Q2:
Pretty much dead for NA/INT servers, since this is already locked on KR. Dunno if this game is still available on JP server.
@KuRoNeKo That notice is over a year old (and is out-of-date anyway - there have been updates since then). It's also mistaken in multiple ways:
The pajama characters were already in the game and available before that update, they're just technically EP14 cards.
The pajama characters are obtained via the cafe, not the (currently missing) coin shop.
Sorry, I'm not too familiar with the 100dp format, most of my experience comes from 250-300dp decks. My general impression was that passcode swarm was the most popular deck and comprised of the majority of the metagame.
If snowball/multi-follower buff decks are popular, then yes, this deck will have a field day with them. If the majority of the metagame at 100dp are these kinds of buff decks, I can see why the op would think this deck is one of the best, since it does counter them easily. The deck isn't the strongest by far, but it does fit into the metagame.
