Sorry to everyone for the late reply, I've taken a break from mtg with the pandemic.

SlimeSolo759 probably you don't remember you even asked a question, given I'm replying months later, but the idea of the deck is to have a high land density (~70-75 lands) thus allowing you to survive the combo if you have enough life, also there are cards that prevent Belz's dmg from happening by giving him lifelink (such as Whip of Erebos ) in case you go bellow the life needed.

ThassaUpYo@ssa Thank you for following the decklist! Well, Sibsig is a bit complex to use but it has three advantages over other cards, 1) It allows you to combo off when no forest is in play 2) It gives recursion if the combo is interrupted 3) this recursion is creature based, which is dodges some common non-creature interactions.

Scott-Spain Definitely a card worth considering :)

Great job on the updates! You pretty much made all the changes I would've recommended. I replaced Boompile with Introduction to Annihilation because I have bad luck. lol

Hagra Mauling  ^Flip is another piece of removal to add to the list as well.

Looking ahead, I think we could add Treasure Vault, but it's also a bit risky.

Anyway, welcome back! Hope everything is going well!

Scott-Spain Thank you for the suggestions both added to the maybe board. As for Treasure Vault, it is not the best ramp land, but it is a ramp land nonetheless, defensively better than a swamp. I will add it when the set releases.
