I have other TwinSmith Musket combos that require more main deck investment from muskets which offers a great top end but lower consistency. This combo is for if you just run a minimal musket package(3 main deck cards, 2 ED), lose out on the Musket disruptions but increase consistency.

You want 2 open spaces in the main monster zone at the end. 1 for A Bao to return to and then the other free space for the twins. Mutiny in the Sky's gy effect can clear an extra fiend off the board otherwise on your following turn the twins can be used for "free" to return it your hand.

Nibiru: Depends on when dropped. Being Fiendsmith it can still make a board via engraver + nib token.

Droll: Combo has 2 draws and 1 add. The 2 draws are optional. If you skip them then this can play around droll.
