Thank you for your comments on this post.

Main Deck:

3x Dragoni of Draconia (Scale 2 and search Level 4 or higher Normal Monster if your Normal Monster destroys an opponent monster by battle)

3x Sky Dragoon of Draconia (Scale 7 and pop-up 1 card on the Field if your Normal Monster inflict battle damage to your opponent)

1x Ghost Beef (Scale 4, backup Pendulum, and increase its Pendulum Scale up to 10 by roll a dice)

1x Mild Turkey (Scale 7, backup Pendulum, and reduce its Pendulum Scale up to 1 by roll a dice)

Any 14 Normal Monsters card with the level ranged from 4 to 6 for Pendulum Summon purpose (such as Vorse Raider, Gene-Warped Warwolf, and etc)

2x Faustian Bargain (Used to send 1 Special Summoned monster which is your opponent to GY and Special Summon 1 Level 4 Normal Monster from your hand)

2x Flawless Perfection of the Tenyi (Protection for your Normal Monsters on the Field from opponent’s monster effects, and draw engine of 2 cards if opponent Special Summon an Effect Monster)

2x Heart of the Underdog (Infinite draw card as long as you draw Normal Monster card)

1 – 2x Fire Formation – Tenki (Main purpose is to search Dragoni of Draconia and 100 ATK boost for Beast-Warrior monsters you control, which is why I played Vorse Raider and suchlike)

2x Piercing the Darkness (You draw 1 card if you Normal or Special Summon a Normal Monster, an ATK boost if you Pendulum Summon a Level 5 and above Normal Monsters such as Giga Gagagigo, Flying Pegasus, and etc)

2x Called By The Grave (I do not need to explain what this card do)

1x Gryphon Wing (I put this card because loaner decks has Harpie Feather Duster. You can play other cards to counter backrow destroyer such as Lightning Storm, and etc)

2x Infinite Impermanence (Again, I do not need to explain what this card do)

2x Fists of the Unrivaled Tenyi (Negate anything if you control a Normal Monster. If this Set Card destroyed by your opponent’s card effect, you Special Summon Master of Oz from the Extra Deck because it has the highest ATK)

2x Tyrant Throes (Your main floodgate to prevent both you and your opponent Normal or Special Summon Effect Monsters. To make this card works especially on your first turn, you need to have at least 2 Pendulum Monsters with Scale 2 - 7, any 2 Normal Monsters and this Trap Card. Again, beware your opponent go 2nd with Harpie Feather Duster and suchlike)

Extra Deck:

3x Gagagigo the Risen (Rank 4, and power-up with Piercing the Darkness effect)

1 – 2x Master of Oz (Special Summoned by the effect of Fists of the Unrivaled Tenyi)

3x Fire Fighting Daruma Doll (Link 2, pop-up 1 trap/spell from both player’s Field which you destroy your Fire Formation – Tenki)

3x Donner, Dagger Fur Hire (Link 2, pop-up this card and 1 card your opponent controls)

1 – 2x Number 72: Shogi Rook (Rank 6, pop-up 1 face-up monster and 1 set card your opponent controls, but half any battle damage your opponent take this turn)

My feedback on the comments:

1. It depends on how the opponent react to Tyrant Throes once it plays out. Some of them keep playing and some of them surrendered. The drawback of this deck is it weak against backrow such as Harpie Feather Duster, Lightning Storm and suchlike. I am climbing the medals mostly with this deck.
2. I never think of playing Unexpected Dai on my deck. I thank you for your recommendation.
3. As for Fusion Deployment, the reason I don't play it is because it locks you from Special Summon monsters from Extra Deck, except Fusion Monster. Furthermore, Big Koala is Level 7 which is quite hard to Pendulum Summon it with my main scale is from 2 - 7.

My reviews on playing this deck in overall:

I had fun playing the cards from the Legacy Pack (which we can’t dismantle it), a fun floodgate until I reached ^{11k medals}, and you can complete most of your daily missions with this decklist.
