Demise/Evil Hero OTK

Looking for some feedback on my deck

Monsters 21

3x Demise
3x Masked Beast
3x Valkyrion the Magna Warrior
3x Blue Eyes
3x Sonic Bird
3x Manja of the Ten Thousand Hands
2x Senju of the Thousands Hands
1x Morphing Jar

Spells 15

3x Dark Calling
3x Trade In
2x End of the World
2x Magical Mallent
1x Advance Ritual Art
1x Card Destruction
1x Megamorph
1x Monster Reborn
1x Sword of Revealing Light

Traps 4

2x Threatening Roar (Ran out of ideas here)
1x Mirror Force
1x Torrential

For those of you who don't know you basically just get Demise, Advance Ritual Art, and Dark Calling in your hand with the Masked beast and Valkyrion in the Graveyard and then you basically win.

Use Reasoning and Monster Gate, it will plow through your Demise, Valky and Masked Beasts. then you're good for Dark Calling

You may want to use Royal Decree incase the other have Solemn Judgment (Or just use the Solemn and Bribes)

I don't like any Demise OTK with The Masked Beast. They're pathetic and if you want me to show you a better one just duel me. My version never exceeds 5 turns and almost 80% of the time I win on the 2nd turn of the duel!

Your grade for this OTK is a C

oh, so this is a demise/gaia OTK deck lmao!
