If you are already planning on attending GP Vegas, you may want to consider bringing another deck for the free tournament I am running at the event.
You can find the details
here.
The format of the tournament is what I'm calling
Vintage Artist Constructed.
You'll need a Vintage Deck, but with the additional restriction that the cards be illustrated by a single artist, basic lands included.
Before you declare the artists that illustrated power the champions, you'll want to check out their mana bases first. You might be surprised.
Several artists have some pretty strong deck possibilities, but none are obviously dominant (although Christopher Moeller is borderline).
I think this will be a fun event and brewing for the tournament should present a fun challenge for you, if nothing else.
I look forward to seeing what everyone brings and meeting y'all in Vegas.
