1 "Buster Blader" + 1 Dragon-Type monster Must be Fusion Summoned and cannot be Special Summoned by other ways. This card cannot attack directly. This card gains 1000 ATK and DEF for each Dragon-Type monster your opponent controls or is in their Graveyard. Change all Dragon-Type monsters your opponent controls to Defense Position, also Dragon-Type monsters in your opponent's possession cannot activate their effects. If this card attacks a Defense Position monster, inflict piercing battle damage to your opponent.
Good attack and defense, and can be increased higher if your opponent uses Dragon-type monsters.
Very strong against Dragon decks since it will negate their effects, and switches them to defense position.
Deals piercing damage when attacking defense position monsters.
Fusion summoning this card can be easy if you use fusion substitute monster, since you can use any other dragon type monster as the other material.
Can't attack directly.
If you are using a dragon deck, and your opponent takes control of this card (through cards like Enemy Controller), it can potentially one shot you if you don't have any protection.
If your opponent does not use any Dragon-type monsters, it is just a high attack monster that can pierce defense position monsters, but can't attack directly.
Without needing to bring Buster Blader, you can use any Dragon-type monsters to fuse into the Dragon Destroyer. This can make it more versatile and much easier to summon. Red-Eyes B. Dragon now can be used to fusion summon into 3 different monsters, which can make it versatile, especially since Red-Eyes has its own supports as well.
Changes Battle Positions
Prevents activation of your opponent's Effect Monsters
played against a Seto running dragons, who started his turn owning the field with a 3k dragon and another 4* dragon vs my 1 dragon. He summons darkflare dragon, uses his effect to drop Kidmodo to his graveyard, and summons a Blue eyes...so 3 high atk dragons..but can't attack that turn.
I have 1 card in my hand (buster bladder), my next draw is Poly...game over. The dragon destroyer arrived on field with over 7k attack..
This has so much OTK potential, even against non-dragon decks. Summon him and with either Mystic Box or give and take, give your opponent a Poki Draco. That's 3600-3700 damage, plus an attack with another monster such as Mirage Dragon and that's game.
More than likely because the fusion sub has a specific card they're subbing for (buster blader) when you have a dragon in your hand whereas having bb in your hand, the sub monster has no specific card to sub for this not becoming a dragon type
Are you trying to Summon it by tributing The Light Hex Sealed Fusion and Exploder Dragon? Because if you are, that is not a Fusion Summon, and this card must be Special Summoned by a Fusion Summon. You should be able to use Poly with Exploder Dragon and a Fusion Sub though
Why I can't destroy this with Devine Wrath? Although it's effect is activated when I summon a dragon monster and it's changed to defense position.
