I just made a jurrac deck too
id put 2 ptera instead of staurik or one of each...
That way youll get a lvl 3 non tuner which is nice with a lvl 2 tune like brachis or preferably Garim
Then i would take out one of your fossil dig or one sarcophagus for a pot of avarice that way you can do more synchro without having to tribute solidarity forever
I would also exchange one horn for hunting instinct to get herra even more easy
You could consider to add Gozen Match too nice card for deck like frogmonarch
Mine is going pretty well we could do a Jurrac war if you want
