How do you summons Blue-Eyes Ultimate Dragon in Yu-Gi-Oh?

Here are your options: * Fuse 3 "Blue-Eyes White Dragon" ("BEWD") cards with "Polymerization", "Fusion Gate" and/or "Dragon's Mirror" * "Cyber Stein"'s effect (pay 5000 LP to Special Summon a Fusion Monster from your Fusion deck) * Use "Light Hex Sealed Fusion" and its effect and tribute it along with 2 "BEWD"s on your field * Other Fusion Substitute Monsters can be used in the place of one "BEWD" (except in the case of "Future Fusion" where all 3 "BEWD" cards must be sent from your deck to the Graveyard)
