Not half bad actually.

....What kind of sorcery is that???

well, on the decklist,
1st, you have little reason not to run heavy storm, run it. maybe take out 1 mini guts, since well....it'll be dead draw sooner or later and at 3 implying you can keep it live anytime. either that, or triple mst. you'll need some kind of reliable S/T hate, like really.

2nd, you might want to put an extra Umbral Ghoul to increase consistency. If you do, you can adjust the extra deck to accomodate additional Xyzs. Also Recurring Nightmare is a great addition, mainly that you have many targets for it(umbrals, viper, vaskii).

3rd, burial here seems not very good actually, take it out for mst

4th, double starlight road will often be dead. settle for 1 or kick it completely.

Maybe that's it for now, you should test it in like 5-10 duels to see how consistent it is.

Good suggestions, i'll test it with that
