Archmage Ascension + Gilder Bairn would be a good combo, but I'm not sure you'd want to have to put Gilder Bairn in there.

You need Soramaro, First to Dream. His power and toughness are each equal to the number of cards in your hand. He has flying. You can pay 4 (colorless) to return a land to your hand and draw a card. Also, Seer's Sundial - Its landfall ability lets you pay 2 and draw a card whenever you play a land. I think it costs 2 or 3.
Izzet Boilerworks forces you to return a land to your hand when it comes into play. It isn't worth it if you've got walking atlas or Terrain Generator. All the other ones are good though.
Yeah, I realized the isochron scepter + glimpse the unthinkable problem a while back, but isochron is still good with Tome Scour.
Nice cards. Unfortunately, with 99 different cards, you'll never get the one you're looking for. Try putting in multuples of your "trump" cards. I applaud you for putting in Thran Dynamo. It's possibly one of the best cards in the game (it's among my top 5).
