III. BOSS MONSTERS & THE POWER OF DESTROYING THE FIELD
Thunder Dragon Colossus (x3)




DARK
8Thunder Dragon Colossus
ATK:
2600
DEF:
2400
"Thunder Dragon" + 1 Thunder monster Must be either Fusion Summoned, or Special Summoned during the turn a Thunder monster's effect was activated in the hand, by Tributing 1 Thunder Effect non-Fusion Monster (in which case you do not use "Polymerization"). Cards cannot be added from the Main Deck to your opponent's hand except by drawing them. If this card would be destroyed by battle or card effect, you can banish 1 Thunder monster from your GY instead.
This card can be easily summoned by Tributing any Thunder monster on the field, provided you have activated the effect of a Thunder monster in your hand that turn. You only need to activate it once. If you have multiple Thunder monsters on the field but only have one effect activated in your hand, you can turn both of them into COLOSSUS .
This wife's strength lies in this:
Protection: He can protect himself from being destroyed by card effects by banishing a Lightning monster from the Graveyard.
Floodgate: Your opponent is not allowed to add cards from the Deck to their hand (Search).
However, what makes it "fairer" in Duel Links is that this effect doesn't interact with Skills . Skills are still allowed to search for cards even when COLOSSUS is on the field. So, many decks can counter, counter, or completely ignore this monster's effect. But there are still some decks out there that will truly "cry out" because of this effect.
Thunder Dragon Titan (x2)




LIGHT
10Thunder Dragon Titan
ATK:
3200
DEF:
3200
3 "Thunder Dragon" monsters Must be either Fusion Summoned, or Special Summoned by banishing 1 Thunder monster from your hand and 1 Thunder Fusion Monster you control, except "Thunder Dragon Titan" (in which case you do not use "Polymerization"). When a Thunder monster's effect is activated in the hand, even during the Damage Step (Quick Effect): You can destroy 1 card on the field. If this card would be destroyed by card effect, you can banish 2 cards from your GY instead.
Summon: Use THUNDER DRAGON FUSION (mix 3 Lightning from Graveyard/Exiled Zone back to Deck - greatly restores resources) OR banish COLOSSUS on the field + 1 Lightning from your hand.
Card Destruction Effect: If a Lightning monster's effect activates while in your hand, you destroy 1 card on the field (NOT targeting). This effect is NOT once per turn .
How to use: If you have DRAGONDARK or DRAGONMATRIX in your hand (both are Quick Effects), you can activate them during your opponent's turn to have TITAN bombard their field.
Protection: Protect yourself from destruction by banishing any 2 cards from the Graveyard.
Chaos Dragon Levianeer (x3)




DARK
8Chaos Dragon Levianeer
ATK:
3000
DEF:
0
Cannot be Normal Summoned/Set. Must first be Special Summoned (from your hand) by banishing 3 LIGHT and/or DARK monsters from your GY. When Summoned this way: You can activate this effect; apply the following effect, based on the Attribute(s) of the monsters banished for the Special Summon, also this card cannot attack for the rest of this turn. ● Only LIGHT: Special Summon 1 monster from your GY in Defense Position. ● Only DARK: Shuffle 1 random card from your opponent's hand into the Deck. ● Both LIGHT and DARK: Destroy up to 2 cards on the field. You can only use this effect of "Chaos Dragon Levianeer" once per turn.
Summon: Exorcise 3 Light/Dark monsters from the Graveyard.
Power:
Exorcise 3 Dark: Grabs (shuffles) 1 card from your opponent's hand into their Deck (Extremely powerful when played first).
Exorcise 2 Dark / 1 Light: Destroy 2 cards on the field (non-target).
Double benefit: Exiling the THUNDER DRAGON from the Graveyard to summon LEVIANEER (or to protect the Boss) will also activate their effects. Kill two birds with one stone!
Skill
Mystical Elf (50% )
The PRINCESS ADENA'S PROTECTION skill is essentially placing a MYSTICAL ELF on the field for free.
Effects:
Provide 1 Light monster (good for Levianeer ) and it's Level 4 (for Xyz Rank 4 monsters like Gallant Granite to find Nibiru ).
Most importantly: If you control MYSTICAL ELF , you draw 1 card, then look at the first 2 cards in your hand and add 1 card to your hand.
Why use it? THUNDER DRAGON is very prone to bricking. This skill helps unbrick your deck and adds a powerful new card.
Note: Use deck filter cards (like the original THUNDER DRAGON ) before activating the skill to increase your chances of drawing a good card.
Destiny Draw Leading to Dragon Master Knight (Skill Card) (50% )




Destiny Draw Leading to Dragon Master Knight (Skill Card)
ATK:
0
DEF:
0
You can only use this Skill's first and second effects once per turn (1 effect per turn) and once each per Duel. 1: Can be used before your normal draw. Play 1 "Blue-Eyes Ultimate Dragon" from your Extra Deck in face-down Defense Position and send 1 "Black Luster Soldier" from your hand or Deck to the Graveyard. One of the cards from your normal draw this turn will be "Ultimate Fusion". 2: Reveal 1 LIGHT, DARK, or EARTH monster, or 1 "Ultimate Fusion" from your hand, then either place that card on the bottom of your Deck or send it to the Graveyard. Then, draw 2 cards.
Ignoring the initial effect of Skill 2, which allows you to shuffle or discard Light, Dark, or Earth monsters to draw 2 cards (while simultaneously filling the graveyard for Chaos Dragon Levineer ). That's all you need to know. This can help us send items to the graveyard to banish monsters or return bricks to the deck, but the important thing is that it's an easy and convenient draw to help us set up plays.
COMBO & HOW TO PLAY
This isn't strictly a rigid combo deck, but rather an interaction between the cards. However, there are some standard playstyles:
1. Combo with ALOOF LUPINE (Best Starter)
In hand: Requires ALOOF LUPINE + ( DRAGONDARK or DRAGONROAR ).
Perform:
Summon ALOOF LUPINE , banish 1 monster from your hand (e.g., DARK ).
Remove any remaining cards from the deck (e.g., ROAR ).
Both activate: ROAR summons DRAGONMATRIX from the Deck; DARK searches for DRAGONHAWK (or FUSION ).
Link LUPINE + MATRIX -> I:P MASQUERENA (or GALLANT GRANITE ).
MATRIX descends into the grave to find another copy.
Use HAWK to revive a Lightning monster -> Upgrade to COLOSSUS .
Next, upgrade to TITAN (Exile Colossus + Lightning on hand).
Result: You have TITAN on the field and MATRIX in your hand (Quick Effect) to unleash a barrage of attacks during your opponent's turn.
2. Combo with GOLD SARCOPHAGUS
This is a great starter because it doesn't cost any Normal Summons.
Use:
If you don't have Hawk: Expel DARK -> Find HAWK . Use HAWK to revive DARK -> Go to COLOSSUS .
If you already have Hawk: Banish ROAR -> Summon DARK to the field. Use HAWK to revive ROAR . Link those two monsters into I:P or GALLANT to activate the search effect.
3. Ahead vs. Behind Thinking
Go First: Prioritize using LEVIANEER to banish 3 Dark Cards and rip cards from your opponent's hand. Set up TITAN + I:P MASQUERENA (or GALLANT with NIBIRU to counter Book of Eclipse).
Go Second: This is an extremely powerful board-breaking deck. Use Levianeer to destroy 2 cards. Use the effects of your Lightning monsters to activate Titan to destroy more cards. Use Thunder Dragon Fusion to recycle resources endlessly.
How to Build a Deck
Why? Because this deck is very easy to brick. If you draw too many Staples without an Engine, you're doomed.

Summary
THUNDER DRAGON is a decent deck. It's not the strongest deck in the game (it's easily countered by BOOK OF ECLIPSE and COLOSSUS is indirectly nerfed by its skills), but it's SUPER GOOD at disrupting the field and farming resources.
You don't need to invest in it if you don't have cards yet, but if you already have cards, it's incredibly fun to play.
Thanks for reading this guide, have a great day <3
