So the Goal is to get out Chaos Max, and attack once for Game. Depending on your opening hand, you can get fully set up but most cases you will have to get stuff set up and win the following turn.
Blue-Eyes Abyss Dragon is Key, but to get its effect off you need to make sure you have a Blue-Eyes on the Field or even easier in the GY.
So your objective is to get the Blue-Eyes to the GY, either from Foolish Burial, or dragon shrine. Dragon shrine is clutch because you can get one in the GY, then send an additional dragon since you sent a normal monster first, and you send Stone of Ancients which will help you special summon Abyss at the end phase. So i will usually get out a linkuriboh and chill. Depending on your hand you can go into xyz or even Alt Ultimate Dragon, but most cases you will end with a linkuriboh and possibly a Imperm Set.
Then in the end phase, your Stone of Ancients will activate, special summon the Abyss dragon (I usually do in defense), which in turn will activates abyss effect which you search your Advanced Ritual Art, and the Chaos Max dragon. Now if you have either of those in hand or its more ideal to get a poly then go for it, but in this example you don't have either card.
So next turn you will have an empty board, most likely they killed off your linkuriboh. So you activate Advanced Ritual Art sending the Dragon Core Hexer to the GY, Summoning the Chaos Max Dragon. Now you should have more then enough Monsters in the GY by now, and in the case of this example you have searched or had Chaos Dragon Levianeer in hand already. So what you do is banish 3 light monsters, don't banish the Dragon Core Hexer we need that, summon out your Chaos Dragon Levianeer, activate its effect special summoning the Dragon Core Hexer in defense. Now you can synchro the Chaos Levianeer and the Dragon Core Hexer to make the Phantasmal Lord Ultimitl Bishbaalkin.
Now when that monster gets summoned, you can activates its effect to summon out tokens (o atk, 0 def) to your side of the field, and your opponents side of the field, the amount of tokens depends on how many monster zones are open. Its fills the remaining zones. So now your opponent has atleast 1 token, attack with Chaos Max and game over (8000 Damage).
This isnt some meta beating deck, buts a hell of alot of fun to play. I forget who i saw this strategy from but i changed it up some.
Any way to make it better feel free to comment or message, im no expert and don't know everything so give me some new ideas.
