In green, there's also Life from the Loam. Not technically a "draw" engine, but it is a card advantage engine. Red is a little more varied...off the top of my head I can think of Chandra, Torch of Defiance, Dreadhorde Arcanist (though this is reliant on other draw spells), as well as underpowered things like Faithless Looting. The only one that comes to mind for White off the top of my head is Palace Jailer.
I'm sure there's lots of others, but these are the ones that come immediately to mind.
@evouga Yup. Here's confirmation:
The disqualified player in question is former VSL competitor and Vintage stalwart Andreas Petersen. Not a good look for him in any way. Glad WotC took the appropriate action.
