Forum:Advice with Spellcasters

Hey, everyone! This may be a pretty broad question, but I am looking for a little help. I'm looking to get back into the Yu-gi-oh TCG after being away for about six years. I always loved the spellcaster cards, and after searching through the internet it looks like you can still make a mean spellcaster deck. The only thing I don't totally understand is what cards are legal. I'm not a pro and have been away so long that when I go to the website and they just list off a bunch of boosters and deck builders as legal I don't really know what is what. If I was to make a spellcaster deck I could still include classics like dark magician, dark magician girl, sorcerer of black chaos blah blah blah, you get it. So, if anyone could give me a heads up on what cards are legal right now, or even a link to a couple examples of spellcaster decks that would be fantastic! Sorry if this is hard to answer or in the wrong place, or, whatever. Thanks in advance.
