"Guardragon Gusto" Deck 2020

Playing

A Deck that aligns Sphered and Gard with Evhari Guardragon.
《Draconnet》, Expected GUY, 《Emergency Teleport》, etc. If you can get Eve with a 2-star normal dragon tuner, you can attack Sphere by the following route.
Search and activate his Guardragon in World Legacy with Eve's effect to revive the dragon.
Eve + Dragon → Harifiber, Recruit Guardragon of the World Chalice with Eve effect, Gard with Harifiber effect.
The World Chalice's Guardragon → Elpy, World Legacy's Guardragon moves Elpy under the Harifiber, and uses Elpy's effect to recruit Black Spear.
Black Spear → Pisti to revive Black Spear again, Elpy + Pisti → Romulus to search the valley.
Halifair + Romulus + Garde → Skaldet, Special Summon the Dux searched in the valley with the Skaldet effect, and GY's the World Chalice's Guardragon effect to revive the star 2 normal dragon.
Revive Gald in Attack Position with Black Spear, Dux + Star 2 Normal Dragon → Gajargu, Glyph Search with effect and go straight to GY.
Recruit Pirika with Glyph effect, revive Black Spear with Pirika effect, Pirika + Black Spear → Spheread.
Collect Pirika or Glyph with Sphere effect. (Glyphs are also discarded in the ravine next turn)
Final stage: Skaldet, Gajarg (+300), Spheread (+300), Garde
His 3000 ATK can be suicidal with his Gusto for a total of 8000 damage.

Strength

His Gusto special attack will line up in the second attack with a reasonable probability.

Weakness

Since Gusto's special attack is weak, it is difficult to attack if the opponent's RBI is low without Kaiju being drawn.
Extras other than those used in combos are for when you fail, so I'd like to find a configuration that can switch well.
Also, since it is a second attack type, it is painful to have to break through the opponent's interference.

Customize

Regardless of Guardragon, it may be possible to move in the closed direction by mixing with WW and sound.
If you have any advice, please let me know.
Please let me know if there is a smarter route.
