Just some of my small opinions:
Manju of the Ten Thousand Hands
is much better than Sonic Bird
I'm not keen on Rainbow Life
but if you wanted something similar than maybe something like Draining Shield
Mask of the Accursed
just doesn't work these days since monsters float way too much.
We kind of need to figure out what it is you are doing.
Are you going for a pure Lava Golem
turbo type deck or are you doing a Ritual Relinquished
deck mixed with Lava Golem Support?
There is a lot of new ritual support from the new Impcantation archetype.
Some good cards to compliment a ritual deck:
Impcantation Secret Study
Some new Relinquished support:
Illusionist Faceless Magician
I'd remove all the Kuriboh
monsters and spells.
I'd remove Nimble Musasabi
I'd remove The Unhappy Girl
I'd remove Rai-Mei
. Destroyed by battle effects in modern Yu-Gi-Oh! just aren't great.
100% remove Hinotama
. Not nearly good enough.
I've made up a quick test version of something that might be useful to you. It's a Ritual/Lava Golem deck with some generic staples:
Something that is definitely a test is Deck Devastation Virus
. If you have Lava Golem on your opponents side of the field, summon Relinquished and capture it and then tribute it with Deck Devastation Virus. Definitely more of a test though, if you end up liking it then I'd recommend removing Royal Decree
Still a LOT of room for improvement in this version but it is a start:
