Just a deck I'm messing around with in Arena. Still have a couple of lands to get, and I'm looking to further refine it. Seems to work reasonably well.

Beamsplitter gives additional value from Quasiduplicate on anything, two card draw for one mana with Rile, 6 additional trample damage with Run Amok. And when you have a Beamsplitter with Murmering Mystic on the field, Quasiduplicate is off the charts levels of advantage.
