MY favorite is the Black magic attack. I really want it, it would fit in with my darkmagican deck.

I Like Dark Magic Attack, Mage power(Which I don't have yet) Pot of Greed,
and probably my best would be
DIFFUSION WAVE MOTION!!!

DIFFUSION WAVE MOTION! Nothing like having your high level Spellcaster (Such as... Dark Paladin!) Annialating your opponents monsters!

Spellcasters Rule!

creature swap hands down. playing creature swap while i have a sinister serpent on the field is one of my best combos

monster: BEWD LOB (Because it was my first)
Magic: tie between HFD and Monster Reborn
trap: CotH

You are deffinetly right! Spelcasters are the best! I have a dark magician deck with a dark magician girl, 2 skilled dark magicians, a dark magician oh chaos, and a sorcerer of dark magic. with magics like tribute dolls, and contract with the abyss. and final countdown and wave motion machines. and soul of ressurection to bring in a dead normal monster. i would pute in dark palidens but i don't like to use fusions cause there hard to use. in my schools card club i have one every mach sofare and every wins bin with my dark magician deck. they rock.

change of heart is one of the best cards in the game! it is versatile and can help you summon your highlevel mon and get rid of your opponents at the same time! your opponent tributes two of his mons the get his best out and you pull a change of heart on your next turn to tribute his best for one of yours and see how mad you make em! this is esspecially good in adv. where monster reborn is not an option. not that the strategy would always work considering that some high levels (and even some low levels) are unnafected by spells or cannot change ownership under any circumstances.

i like raigeki cause whats better then destroying all you opponents monster?

for me, it'll have to be riyoku. decrease one monster ATK by half, increase one monster ATK by the same amount. just take the highest monsters atk, increase your strongest monster, and then attack thier weakest monster. too, too sweet.

Toon World is my favourate spell card of all time, EVER!!

I am gonna have to say Different Dimension Capsule. There is nothing worse than having 3 BEWD and a flute and no Lord of D. ,or Lord of D. a flute and no high level dragons to summon. This little card comes in quite handy in a spot like that. I use 3 of 'em in every deck I build.

I'm not sure, I got a lot of favorite magic cards. Some just for their looks, some for effects.

I'd probably have to say....

Devils Sanctuary all the way!!

Normal Magic Card
Special summon 1 "Metal Devil Token" (DARK/Demon/1/0/0) to your side of the field. The token cannot attack. Damage done to the controller's lifepoints as a result of battle with the token is done to the opponent instead. You must pay 1000 Lifepoints during each of your standby phases. If you cannot, destroy the "Metal Devil Token."

Basically, you get a free monster/wall that you can tribute if you wish and it only costs 1000 Lifepoints which isn't that much these days.

Pot of Greed! It is necessary in most decks and it can help you out in a duel in almost any situation that you are in. Also drawing 2 cards for the price of 1 is good because it can help you get what you need faster.

3 words : Pot Of Greed :P , It's a fantastic card , and no deck is complete without it . Thanks to my Black Magician of Chaos ( For anyone still complaining about me using Japanese names , I'm sorry , I just preger Japanese card names >_> , what's wrong with that? ) , I can bring it out twice in a round.
