White Forest (ALIN)

Quick summary:

Diabellstar+Wanted are starters thanks to the new Magistus Chorozo. Ty-Phon is a nice Ultimate Slayer Target. Post ALIN, I predict Maliss will be good so we are keeping the Lancea in the side. I like spell non-engine in this deck, but it should be mentioned this deck searches veiler so it is a decent idea to run at least one. Final Bringer of the End Times is a neat pick cause as you continue to recycle your white forest monsters on your oponent's turn you can turn them into pops with it. As for everything else...

New support is interesting and really opens up a pretty great strategy further. Only issue is the field locks you out of darks, but usually by the time you get to Poplar, you have gone through the Azamina line, this is largely due to the aforementioned Chorozo line. Wanted, Diabell, Deception, Hallowed, Mu Rcielago, Elzette, then go into Chorozo, Elzette and synchro to a 6, usually Rciela. This is 6 starters on top of the 9 white forest already had. This gives me the confidence to go over 40, though you can cut down on cards as needed if you want to stick to 40 or cut the Chorozo. The lock is not a big deal because making Chaos Angel or Chimera is not a part of the end board. Cards like Chengying and Executor are not effected by this lock which is really cool... or thematic, whichever one is better.

On the other hand if you start with the deception and a way to Diabellstar, just search the new Diabell cause it's a sinful-spoil card.

Chaos Angel is a bit interesting in this deck, you can make it with a variety of 4s and 6s using Azamina cards and White Forest Synchros. I chose Mudragon as a Super Poly Target so I can change it's attribute to get a max defensive Chaos Angel out, though you may want Garura instead, it would work with the Silvys and Rucia in deck. Guardian Chimera is a really cool addition to this deck and I love the Quickplay fusion alla Chimera Fusion that can really take your opponent by surprise.

As for the Ratios, we are running 3 of the starters then 1 of the cards we wanna find later. You can argue down or out the Astellar, but at that point I would maybe just insert more non-engine like main decking the Super Poly or Drolls. Possibly add a second Tales. Possibly cut some of the field spell as well. 

Overall, I did a few test hands with this and it has not bricked once, it sucks drawing into the white forest one-ofs until you discard them for cost, every card in the deck feels nice cause its very insular and can search and weave between the three engines plus the white forest pitch makes them all useful in some way.
