The Deck works pretty fast. Incredibly fast. LS are good to mill out Fabled monsters + they are useable for Arcanite or Tempest Magician as a material.

Fabled are just a pretty good engine and combo well with each other, plus they are in a good place while they are in the Graveyard - or in my hand.

Beckoning Light is pretty useable here: can activate the effects of Fabled monsters, can fill the Graveyard (even for Pot of Avarice), or can recycle useable cards like Honest.

-1 Lyla
-1 Kushano (Only 2 is required, generally)
-1 Soulkios (You do realize his effect doesn't activate Fabled effects, right?)

+1 Grimro (Get what you want, when you want it)
+2 The Fabled Ganashia (I find this pretty awesome, personally)
+1 Glow-Up Bulb (Better than Plague)

-1 Mystical Space Typhoon (Seems excessive, with Lylas too. You could Side it)

-1 Avenging Knight Parshath (Cool, but there are better options)

+1 Ancient Sacred Wyvern OR Colossal Fighter

I hope that helps!

Maybe Gold Sarco to search ace cards, it'd allow Judgment Dragon.
