is this still a valid deck in the new meta?

so i made some combos back in November, but not being able to fully complete them due to not having all the parts. now i do, so i want to see if these are still valid combos.
(High Mode) Guilty Longinus Nexus+S  Xtreme'-0
(Low Mode) Vanish Bahamut Over Zone'+Z-6
(Low Mode) Astral Fafnir Tapered Bearing'-10

lmk if these are valid!
