Specific Fusion Material Support

[Seanoow]

Gosh It's been a while, but I've been wanting to make a more consistent way to combine the Buster Blader fusion with Dark Paladin. I have a few ideas on other ways to take this set but essentially I want to start (when I have more time) working on a Warrior-Wizard-Wyvern/Dragon deck.
This card is designed to be a way to include Dark paladin without needing Dark magician.
Also, the Buster Blader fusion is really only good 'Against' dragons (Yes with buster drake its great I know).
But Dark Paladin gains benefits from both players using dragons. So I wanted to give a reason to include more dragons other than the destruction-sword one.
I will also try to fit in more spellcaster support into the deck but for now this card's purpose is to be a consistent alternative to the swamp monsters. Even though it cant substitute for Buster Blader in the Buster fusion, it can still take the place of the dragon required.
Feel free to leave comments and suggestions. :D

 

Couldn't use the picture I made so ill just write in the details

Dragon, Light, Level 2, 600 Atk, 150 Def,
While this card is on the field you can fusion summon a fusion monster from your extra deck using monsters from your hand or field that lists 2 or more specific monsters substituting this monster as one of those materials. The other materials must be the correct one(s). This effect can not be negated.
-If this card is in the graveyard, except the turn it was sent there, you can banish one "Polymerization" or "Fusion" spell card from your graveyard, add this card to your hand.
