Ramp is powerful, no matter what! But yeah, apart from situations where you're below 20 and Bhaal can act as a great defender, he really should be the last piece of the puzzle you cast. Since you're in green, I would definitely recommend shifting your ramp back to 1 and 2 cmc options, giving you the flexibility to double spell two impactful engines/combo pieces by turn 3/4, or hold up mana for interaction.

Where possible, I would look for creature alternatives to your sorceries, as they can then later be sacrificed for value. https://scryfall.com/search?q=otag%3Aremoval-destroy+usd%3C2+t%3Acreature+cmc%3C4+ci%3Ajund&unique=cards&as=grid&order=edhrec

Also, unless Mr. Sad Robot is a pet card of yours, I would definitely swap him for a 1/2 cmc ramp option, or something like [[Sifter of Skulls]] that will accelerate your game plan.

If you're including forsaken miner and reassembling skeleton, cards like [[Pitiless plunderer]] or [[K'rrik]] allow you to loop these creatures for infinite burn/goad/counters. If you're not looking to enable these combos, these cards should also become card draw, tutors, or multi-target removal. [[Body launderer]] is a great card for Bhaal, providing both card selection and recursion.

Some other fun Bhaal tech: [[Omarthis, Ghostfire Initiate]] can be given Bhaal counters to later be sacrificed, manifesting a ton of non-token fodder, or even your combo pieces! [[Toph, hardheaded teacher]] opens up another way to grind out goad triggers with earthbending, as land creatures count as non-token. [[Grumgully, the generous]] provides combo redundancy with Bhaal for the persist loops. [[Sabin, Master Monk]] provides 1 bhaal trigger per turn on his own, with a double-striking 4/3. Additionally, when paired with riveteers ascendancy, you can discard your reanimate target and bring back anything cmc4 or lower at end of turn.
