I realy dont have any suggestions. I found nothing wrong except maybe try out Ohka? I mean, yeah, it doesnt fit the removal theme but it helps Freed and destroys pretty much every playable monster. And White Magical? I really dont like him. SO maybe try:

- White Magical Hat
+ Majestic Mech - Ohka

Great work. Return the favor? Link in sig.

-Shane

try to add a soulf of purity and light great effect and its a light

Wow, Yami nice deck.

Here is my suggestion

- White Magical Hat

He's ok, though I don't like his effect really that much.

- Scapegoat

Clogs the field

- Bottemless Trap Hole

That looks kind of random.

+ Rush Recklessly
+ Rush Recklessly

A great control card. If you don't like the next suggestion. Well this can help WHite Magical Hat.

+ Time Wizard.

He's light. Also a good card. If call right.

Nice Deck 9.5/10.0

Check my deck in my sig.

The only thing i see is that it needs more Mirage Dragon, so...

-1 Asura Priest(the only thing i seen that i would take out)
+1 Mirage Dragon

and i also agree with Ishtar, try out some Majectic Mech's.

Good Deck
9.2/10

- White Magical Hat
- Creature Swap

+ Majestic Mech - Ohka
+ Enemy Controller

Nice Deck
9/10
