This is a fairly generic XiangJian decklist, but one without any stupid card choices. ignore the side deck. extra deck is a bit flexible, some other decent choices are:
draglubion package (with titanic galaxy and numeron dragon) (cut because this deck doesn't struggle otk'ing regardless, and takes up 3 slots)
ruddy rose dragon (graveyard removal, decent choice.
stardust dragon (format dependant but could be useful)
maindeck HT ratios are for Crossout Designator. if not using designator, replace the designator and the 1 of handtraps with more handtraps. something like 3 veiler 2 belle instead of 3crossout 1nibiru 1 veiler would probably be good.
