Tailed Naruto Lv 6 Custom card

This is my Tailed Naruto Lv. 6 Card thanks to for showing me how to make these


Note: in case you cant read the effect (it is small, im sorry) this is what it says:
This card cannot be normal summoned or set. This card can only be special summoned by the effect of Tailed Naruto Lv. 5. When this card attacks an opponents monster in face down defense mode, destroy the targeted monster with out flipping it face up or calculating battle damage. When this card targets a face up defense mode monster with a lower defense than the attack of this monster, the difference is dealt as battle damage to your opponents life points. On the turn this monster destroys an opponents monster card as a result of battle, you may tribute this card during the end phase to special summon Tailed Naruto Lv. 9.
