This deck is from another YouTube channel (
https://youtu.be/nN-_IBxibfI, I felt guilt if I didn't put the link on the description) and this deck is entirely for fun.
First Way:
1: Have any monster in the graveyard to special summon "Exodius the Ultimate Forbidden Lord".
2: Use "Advanced Ritual Art" and dump level 1 monsters while summoning "Demis, King of Armageddon". (Demis can be replaced with other ritual monsters)
3: "Exodius the Ultimate Forbidden Lord" gains 8000 atk!
Second Way (Starting from the stage 1 of the first way, currently with "Exodius the Ultimate Forbidden Lord" on field):
1: Use "Ojama Trio (Or any other effects that place weak monsters on enemy's field) to summon 3 Ojama tokens on enemy's field
2: Use "Diffusion Wave-Motion" to allow "Exodius the Ultimate Forbidden Lord" to attack all the tokens and monsters.
3: For each attack, use the effect of "Exodius the Ultimate Forbidden Lord" to dump normal monsters.
4: You can have 3000 ATK after using the effect on the final token and attack the enemy's monster to deal some damage.
