{Epic Experiment} + {Wheel of Sun and Moon} I can epic experiment as much as I want with no consequences
EDIT: also {Firemind's Foresight} to get it back again
Yeah. I suppose as long as you repeatedly infinite mana loop. More details, or that just sounds like fluff.
Foresight pulls up instant, not sorcery
{vampiric tutor} embedded to a {Panoptic Mirror} + card draw.
Combine the combo with {Karn, silver golem}, {Thran dynamo} and {voltaic construct} for the infinite mana cycle, since you do not need colored mana to play the cards revealed by the experiment... There ya go.
EDIT: course, if you have the Karn combo going you could just use a {Planar Portal} instead of the tutor/mirror to save space
