This card cannot be Normal Summoned or Set. This card cannot be Special Summoned except by Tributing 1 "Blue-Eyes Ultimate Dragon" you control. This card gains 300 ATK for each Dragon-Type monster in your Graveyard. You can negate the effects of Spells, Traps, and Effect Monsters that target this card.
Instead of getting Blue-Eyes Ultimate Dragon through fusion, you can use Cyber-Stein's effect to special summon it. Increase your LP to more than 5000 to use Cyber-Stein's effect when you have Shining Dragon in your hand.
An alternative method to special summon Blue-Eyes Ultimate Dragon instead of fusion summoning. Flip summon Summoner when you have another monster on your side of the field, and when you have Shining Dragon in your hand.
Negates the effects of Effect Monsters / Negates the effects of Spell Cards / Negates the effects of Trap Cards
Cannot Normal Summon / Cannot Set / Nomi / Special Summons itself from your hand
Yeah it will have more ATK if there are more dragons in the graveyard, but the OP anon only says "dragon deck" and did not mention anything about having other dragons in the graveyard
I had a tryhard Kaiba wanker summon this on me, and he thought he had won, with his 4500 ATK. But then I activated my own Polymerization, summoned Ultimate Antique Gear Golem, and owned him with it. I got it to 4900 ATK with one Antique Gear Castle and one Machine Assembly Line I had on the field, and my Engineer had destroyed his Mountain before. The ultimate power belongs to your teacher, dropout boy.
There really aren't, though. The best ways to "cheat" BEUD onto the field exist in Duel Links too. (Summoner of Illusions and Cyber-Stein.) I guess you can copy its name with Supreme King Dragon Starving Venom or Windwitch - Crystal Bell, but both of those would require more deck investment than BEUD in the first place.
BESD is useless, mirror wall, wall of disruption and other traps that don't specifically target one monster still affect this card.
From the wiki: "This card bypasses the usual pitfalls of costs and destruction effects. It essentially has two effects. The first targets your monster when its activated. The second--which only activates after your oppoent is done chaining (if they bothered)--tributes your monster and targets/destroys an opponent's. So, your opponent can't use effects like Prime Material Dragon or..."
"...Stardust Dragon (since nothing will be destroyed immediately). And, if your opponent negates this card, you don't tribute. However, keep in mind that continuous effects still apply. (I.E. You can't target a dragon with Lord of D. on the field.)"
