Slifer the Sky Dragon

This is the third post on the most powerful cards . This one is called "Slifer the Sky Dragon". 
There are two of them like the last one . And this one was owned by a character named
 Yugi Moto and this one was his first God Card.

His atk is 6000 and he is not effected by traps and spells.And the new card is also
not effected by traps and his atk is equal to how many cards are in your hand.
Here is a picture.
