Hiya, and welcome to vintage! Since people are offering sites I usually look at
www.deckcheck.net for ideas for decks or even just to know what is currently winning in the vintage community. You are off to a good start considering you have actually played another format before, just don't forget that vintage and standard are really really different, if you feel brave and make you own deck and don't know if it is good enough or even just want other people to take a look at it you should post it here, if not I think there is nothing wrong with net decking until you can get a good feel for the format and the confidence to build something on your own. Depending on where you live this is also a great resource for looking at up and comming tournaments, though it really depends on what vintage cards you have or can get a hold of. If you plan on going to a tournament that I am at if I have any cards you need I have no issue with lending them to you

. Good luck!!! And welcome to vintage.
