Star Specter, a new Meta???

so, I've been tinkering around the Star Specter archetype and managed to make a small fun deck

then, I just go and join the Pool to try this deck
I then found myself being pitted with Bujin player
It actually surprise me that this deck of mine could win from a tier 1,5 deck with hardly any difficulty at all

this is my deck list:

Monster(21):
Hecatrice x 2
Honest x 1
Nova Summoner x 3
Star Seraph Sage x 2
Star Seraph Scale x 3
Star Seraph Specter x 3
Star Seraph Scout x 3
Star Seraph Sovereign x 3
Star Seraph Sword x 1

Spell(10):
Cards from the Sky x 2
Dark Hole x 1
Mystical Space Typhoon x 2
Rank-Up-Magic - The Seventh-One x 1
Rank-Up-Magic Numberon Force x 2
Valhalla, Hall of the Fallen x 2

Trap(9):
Bottomless Trap Hole x 1
Compulsory Evacuation Device x 1
Dimensional Prison x 2
Mirror Force x 1
Pinpoint Guard x 2
XYZ Reborn x 2

Extra(15):
Bujinki Amaterasu x 1
Cxyz Dark Fairy Cheer Girl x 1
Daigusto Emeral x 1
Fairy Cheer Girl x 1
Night Pappiloperative x 1
Number 102: Star Seraph Sentry x 2
Number 52: Tri-Horn Dust Dragon x 1
Number 80: Rhasrophy in Berserk x 1
Number 91: Thunder Spark Dragon x 1
Number C102: Archfiend Seraph x 2
Number C80: Requiem in Berserk x 1
Vylon Disigma x 1

and for those who just wanted to see the picture:

Spoiler:

this deck's main card, strangely, are not Star Seraph Sentry
In fact, I mostly go for Ouroboros than Sentry, mainly from his useful effect and how easy to summon Ouroboros in this deck, alongside that this deck didn't have the restriction like -Tellaknight on their summoning

please give me some review and how to make this deck better

Haha, a new meta indeed. That's a phrase you should use with caution... especially seeing some of the other new archetypes lately

Well, first of all, -1 Dimensional Prison, +1 Fiendish Chain. Keeping an enemy monster on the field seems to work better for your own Xyz monsters' effects, and anyway effect negation is so useful now I don't have to tell you why. Also, if it were me, I'd try -1 Hecatrice, +1 Valhalla. Because opening with one of each can happen, making your second Hecatrice a useless monster.

This next thing may sound counter-intuitive from reading Sovereign's effect, but even though you can make 3-material xyzs easy doesn't mean you always should neglect the 2-material ones. Honor Ark is ultimately better than Disigma, and Exciton Knight literally makes Thunder Spark Dragon obsolete. Also, if you don't go into Star Seraph Sentry that much, why are you running 2 lol? Try to make some room in there for better choices. My opinions would be:
-1 Thunder Spark Dragon
-1 Disigma OR Papilloperative (not both)
-1 Star Seraph Sentry
-1 Archfiend Seraph
+1 Number 101: Silent Honor Ark
+1 Evilswarm Exciton Knight
+1 Lavalval Chain
+1 Starleige Paladynamo

Also, for a random tech you could try Dimensional Alchemist, but I don't know if it would affect your consistency or not.

Granted you even don't have to take any of my suggestions, but you did ask nicely

keep the butterfly imo

Change:
Hecatrice -1
Star Searph Sword +1

Caster the Avian Skyblaster +1
Evilswarm Exciton Knight +1
Lavalval Chain +1
Number 101: Silent Honor ARK +1
Number 102: Star Seraph Sentry -1
Number C102: Archfiend Searph -1
Number 91: Thunder Spark Dragon -1
Vylon Disigma -1

add Star Searph Sword since its quite useful for a summon fodder more than Valhalla
