Alternate version of Fraction of a Dream #3 that enables it to also act as a win condition through milling while at the same time speeding up the game. I don't claim this is better: 1U - InstantCounter target spell. Its controller looks at the top four cards of their library, puts up to one into their hand, and the rest into their graveyard.
Looks less appealing, but probably more fair, and you've got the mill angle too. Neat.
