Please help me!
I am in need of defeating the final stage of the dark rulers return in the online section.
When it first starts, it consists of the 2 payback monsters and multiple death revenge ones. Afterwards you encounter atrahasis which has same moveset as from offline story ages ago.
Please help me build a good team! I need those gems 
I didn’t have the same monsters as you, however I recommend using using hold ground monsters in your frontline, with bitterbeast who can life flip, and then put stunning entrance healer to 5th slot. What you could try is Titanwolf, Gaiakaizer, Zephyrox and Bitterbeast as your FL. Get Titan and Gaia to critical, then use desperate double and then team turn with Zephy. You want to make sure, that Chronozar and Valza are available for the second phase. Try to keep them stealthed and Valza at 100% HP, and maybe use a give turn monster so he can pour in that sweet buffed CS damage.
Pretty easy fight imo, if you stall for time until his poison leaves, then snooze, dreamhunt, dead.
