Fiendsmith Elvennotes Theory Deck 2

Theorealize can send Medius the Pure from your deck to your graveyard. Medius the Pure’s graveyard effect can shuffle a monster from your field back into the deck to special summon himself, which can clear your center monster zone for your Elvennotes monsters. Theorealize's graveyard effect lets you change the type and attribute of a monster you control, making Chaos Angel and Fiendsmith's Requiem easier to summon.

Fabled Levilazebul is another light fiend that can be used as link material for Fiendsmith's Requiem. You can use Elvennotes Power Patron's effect to increase a Level 6 monster to Level 9, then synchro summon him.

Lastly, I removed Fiendsmith in Paradise because this deck has almost no discard outlets for spells and traps, and it has limited utility while in hand.
