This is a tournament winning deck from GP Santiago it got 3rd/4th out of 660 players. It's also about $60us on deck box probably cheaper if you shop around. This deck will also be valid until the new set comes out in February, but even then there's always a cheap red deck to play.
The BW strategy you're going for is probably okay, but just needs so many more expensive cards to be better. I highly recommend giving the below a shot. It's in the same vein that you're going for now, even though the colors are different.
