Chaos Dragons for Locals

[Nineteen]

Note that I'm planning on using this Deck IRL, so there are limitations to what cards I can put in. For example, I don't own a BLS-EOTB, so I'm using a second Chaos Sorcerer instead. Similarly, I don't have access to Solar Recharge, or any Lightsworn monsters not included in SDDC.

My main concerns are whether 43 is too much or too little for Chaos, whether I should add my third Lyla or third MST to my Main Deck, and if Siding a Cyber Dragon is a decent idea for the current meta. Otherwise, general suggestions are welcome.

I've always thought malevolent catastrophe is underused. It fits pretty well in this deck
