Grade 0s 17:
1 Shining Knight, Millius (best RP starter in Standard)
4 Epona (critical)
4 Llew (critical)
2 Belenus (Sentinel Critical)
2 Iseult/Belenus (depending on your locals' meta)
4 Healing Pegasus (Heal)
Grade 1s 10:
4 Laurel Knight Sicilus
4 Pluck Enchanter (4 is a lot, 3 is fine. I'm still looking through the list for non-Promos I could add)
2 Knight of the Harp Tristan (replaceable with anything you want)
Grade 2s 16:
4 Absolute Blade Knight Livarot
4 Blaster Blade
3 Starlight Violinist
2 Blaster Dark
1 Hopesong Angel
the last 2 G2s can be a combination of Suleiman, another Blaster Dark, Tion, Gordon, anything. I personally like to use 1 Gordon so that my BB columns can hit for 45k (better than Tion if you got 2 BBs) and a 1 of Suleiman
Grade 3s 7:
4 Aerial Divine Knight Altmile
3 Majesty Lord Blaster
This is not a meme build. MLB is a really good card. I'd say it's pretty on par with Altmile, but it's lacking enough RG pressure, even with Gift spamming. Bias or not, I believe Altmile is the better build of the two, for one reason or another. But I see no reason why the 2 builds should not be combined. On Altmile's side, all that you are losing is BSK, who you never really want to ride and only exists for randomly SCing and Suleiman, who albeit is an amazing card, it still can work as a 1 of due to Altmile's toolboxing capabilities and while you are losing G2 Suleiman turns, you are instead getting Blaster Blade turns who attacks for 2 crits. The deck has about 11 Grade 2s with a Vanguard skill, which is insane. Moving on, Pluck replaces both Akane, Dia-connect, Degnuz and Pongal in terms of usage. Tion's numbers are replaced by Gordon (2 45k columns over 1 49k column). Again, Altmile doesn't lose anything of significance by adding the Blaster engine. By adding MLB, you gain the option of having a legit threatening backup who is miles better than BSK. You have the option of going first with MLB, gift spamming (either F1 or F2) and ending it with Aerial. Do note that MLB can also put Altmile in the soul. Alternatively, you have the option of just going full Aerial, ignore MLB, and play as you would have, since, again, I'm stressing it, Altmile's side of things remain the same, you're just removing one bunch of soul chargers and G2 VG skills for another bunch.
CONS: This is an Altmile build. Not a Blaster build. Meaning you won't be getting consistent MLB turns as you would do in an MLB build. If that is your game plan then I'd advise using a pure MLB variant
