This deck likes to go second or at least thats how i built it.
Also the foolish burial goods is in the deck to dump the defense of changban trap card but you could replace the burials with small worlds.
Crossout designator and called by are important pieces of the deck considering it goes second but its great at baiting hand traps and negates.
Lastly you can put whatever you want in the extra deck for the xyz monsters but the link monster is the most important one you absolutely should run everything else is bonus.
