3x Upstart is must have. This playset makes my deck having 37 cards. And I need my best cards to even start playing. That's why I also need 3 unuk. I've seen some builds with 2, but the worst thing you can start with is hand full of traps. Unuk gives you chance to start, with your coth or oasis.
3x Vega? Oh man, people keeps saying me i should play just 1, because it's really easy to resummon with your grave and not good in your hand. That's kinda true and I'm thinking about playing just 1, but still not sure about.
Honest sucks, that's why it went to 2 on the banlist. Yeah, it can be really annoying, but it is also dead when you summon triverr for example, on use raigeki. You are destroying only small fries with monsters attacks, for big monsters u have delteros and mentioned triverr.
I have thought about D.D Warrior Lady. Djinn lock is very annoying combo. I'm gonna test it, but feel like this deck need to stop doing lock instead of breaking it.
I've played Soul Charge and it's not as good as it may seem. Without BP u give your opponent free turn too many times.
Torrential Tribute is a very good trap in this format, when BA is rather not often play (too expensive for it's power level), and when on locals u have to face nekrozes and many low budget decks like yosenju. U can easily side it out when playing with shaddoll, I haven't even thought about removing it.
I have thought about 2 Oasis of the Dragon souls and think I'm gonna play like that. 3 is just too much.
Mirror Force is next very good trap, which may be not useful when playing with Shaddoll, but it is very good for any other deck. Dimensional Prison is much worse now. It's good against nekroz and Qli.
I need many cards to play agains shaddoll, that's why I'm playing 2x SIM (random decks, Shaddoll and BA) and 2x De-Fusion (Shaddoll and Ritual Beast). I think i can put 2x Anti-spell fregnacy instead of 2 Maxx "C", but Maxx is very often so good when u have a situation to play it.
I need Emeral. It's good, makes my deck play. U don;t want Sirus in main. Sirus doesn't gives you anything when u have it in your hand in first turns of a duel. Emeral can be summoned when you need that easily.
Second Delteros also isn't a good idea, in most of the duel you don't even summon it, it's much worse than Triverr.
I'm gonna add New tellar xyz (easy way to get diamond) for number 101 i suppose.
Thanks for all replies! Your advices make me think about the deck and give me new ideas!
