I'd recommend a 17 - 14 - 12 - 7 Ratio if that's ok with you, I'm not going by how Royals are, merely riding wise.

I'm assuming you meant for Alfred to be at 2 here.

Starlight Unicorn is an Akane Target, however the weak 6k boost isn't good, even with the +2k skill. You're better off keeping Marron maxed, because you need 4 Marron.

You don't need Wingal either, 19k Columns are bad against everything.

I won't argue with the Holy Disaster Dragon tech, but you probably want to leave it at 2 and put in a third Alfred.

whoops i meant to put a x3 against alfred

oh derp.
In that case, you can toss in whatever for the extra space or keep Disaster at 3, whatever you want and whatever works.

You can replace one Grade 3 for on Solitary Knight Gancelot if you want another searcher for Blaster Blade.

Reasons.Why I took out 2 Margal was becase it's low defense and it might not go so well if you draw a Grade 3, but I didn't take it out completely seeing as you want the hand advantage.For Starlight Unicorn, I added 1 More Marron, because it's an easy 8000 unlike Unicorn with only a one time skill. Now, I also added Knight of Friendship, Kay seeing as you have a fair amount of Blasters, and it helps since you use Barkgal. I lowered your Akane by one becase 4 is too cloggy and it's not very good when you used counter blasts, I'd mostly recommend 2, I'm even iffy at 3, but it's your deck.
As for your Grade 3 lineup, I added one Alfred Early, mostly because he's a personal favorite of mine, and seeing as you ride Blaster Blade as a Vanguard, it would help you get a unit back to the feild late game when you have used up Soul Saver or weary to discard with Holy Disaster.

Starcall Trumpeter has literally no use but to eat up your Counterblasts even more by calling Blaster Blade. Not only that, but Kay is going to be no use too since Blaster Blade is your only Blaster Vanguard as a G2. Both of those cards work better in a Majesty Lord Blaster focused deck.

Margal's a Draw Trigger and has the ability to slide itself in soul. Playing your cards right, you should be able to get Soul Saver's skill off again if you're desperate and lucky. ... And somehow haven't ended the game yet. Also, if he's running Holy Disaster, he's really going to want Hand Advantage. Llew's 4k is too weak to be ran at anymore than 2 compared to Epona's 5. And you can run 2 Flogal, 2 Sharon.

Wingal's bad.

Since you're not running Toypugal, I don't see a problem with Yusei's suggestion on dropping Akane's number by a bit. You'll want a stronger G2 though, so you can run the other 10k.

Alfred Early is entirely preference. If you want to run him, fine. If not, add an additional Alfred.
