Fabled/DarkWorld Crossover monster

[FiendMaster24]

So I have a deck that's MOSTLY Dark World and Fabled monsters, and, after doing some serious thinking and image searching I created THIS beauty. The idea is of a hideous Dark/Fiend Dark World monster who betrayed Dark World and entered the realm of the FABLED monsters, hiding his hideousness behind a face like mask, and ultimately betraying darkworld. his disdain for darkworld is reflected in his effect, gaining more power the more banished darkworld monsters you have. I just wanted to hear what some of you thought about the idea...

The correct wording would be:

1 "Fabled" Tuner + 1 or more "Dark World" non-Tuner monsters

When this card is Synchro Summoned, banish all "Dark World" cards in your hand and Graveyard; this card gains 1000 ATK and DEF for every banished "Dark World" card. When this card is destroyed, banish it, shuffle all of your banished "Dark World" cards (except this card) into your Deck, and draw 1 card.

 

I will say this card is overpowered; however, this is only when you take its initial effect into consideration. Otherwise, it's kind of tame. Also, if this is suppose to be a traitor of the Dark World, I'd figure it'd be a LIGHT monster (especially seeing how it's a "Fabled" monster).

Thanks for the advice on the wording, Nyx. Also, I considered it but, since he is technically a Dark World monster (who are dark attribute) who switched sides and/or is pretending to be a Fabled monster (who are light) it made more sense to me to keep him dark, since that's what he is deep inside you know? lol
