Notes & Combos

The Nibirus and Bystials haven't really come up yet. They could be Droll or other non-engine instead. They can also be more Performapal Pendulum Sorcerers and optionally Performapal Odd-Eyes Dissolver and Butler. Sorcerer can combine with Vaylantz World - Shinra Banshou to pop random monsters that you start with.

Starting with a random monster + Dragon Shrine that normally sends Darkwurm can be awkward but not unplayable. We can normal summon a pendulum monster and go straight to Beyond the Pendulum. After that, we can use Shrine to dump Darkwurm or Lightwurm to revive with Exceed later in the combo. Nibiru doesn't exist :)

Going 2nd:

Trigger Purple Poison Magician's destruction effect with Electrumite multiple times using Electrumite, Spright Elf, Promethean Princess and Starving Venom. Arc Rebellion XYZ Dragon using Raider's Knight is an OTK option.

In a 1/2 LP duel, we can use a combination of Double Iris Magician, Purple Poison Magician and Supreme King Dragon Starving Venom to easily deal enough damage without clearing the board.

Starving Venom copying Odd-Eyes Revolution Dragon in GY gives it 4800 ATK vs an opponent with 4000 LP. It will have 6800 ATK if they have 8000 LP. After that, one way to get the remaining damage is by using Chronograph Sorcerer's pendulum effect to summon a Timegazer Magician for the missing 1200 ATK.
