Help on Building a Dark Magician/Spell counter deck?

If you have Dark Sage in your deck, you need a Time Wizard in order to summon it, but I wouldn't recommend putting Time Wizard in your deck unless you have some kind of card that let's you flip a coin a second time. One thing I would recommend, though, is that you put Buster Blader, Polymerization and Dark Paladin into your deck.
