This is my quickest way to Fusion Summons:
Twin-Headed Thunder Dragon
-If you have a Thunder Dragon and a Polymerization/Fusion Gate in your hand and the
other two Thunder Dragon in the deck.Activate Thunder Dragon effect,discard this card
(Thunder Dragon) and add 2 Thunder Dragons from your deck.Activate the Polymerization/Fusion Gate effects to Fusion Summon Twin-Headed Thunder Dragon.
-If you have a Thunder Dragon and The Light-Hex-Sealed Fusion on the field.Activate
The Light-Hex-Sealed Fusion Effect.By tributing the Thunder Dragon and this card,you
can summon Twin-Headed Thunder Dragon without using Polymerization/Fusion Gate.
St. Joan
-Activate the Polymerization/Fusion Gate effect while The Forgiving Maiden and
The Light-Hex-Sealed Fusion are in your hand.
-Activate The Light-Hex-Sealed Fusion effect while The Forgiving Maiden is on the
field.You can use Shining Angel to help you special summons either card for a quicker
fusion.
Blue-Eyes Ultimate Dragon
-You can subtitute 1 The Light-Hex-Sealed Fusion 2 Blue-Eyes White Dragon if you
want,but I prefer to Fusion Summon it with 3 Blue-Eyes White Dragon.
Master of Dragon Soldier
-The Easiest way to Fusion Summon it is by using Black Luster Soldier and The
Light-Hex-Sealed Fusion as Fusion Materials (You cannot use The Light-Hex-Sealed Fusion
effect to summon this monster).You can use Shining Angel to get The Light-Hex-Sealed Fusion faster and Manju of the Ten Thousand Hands to get Black Luster Soldier quicker.
