Stillness in Motion
Self-mill has almost always been a means to an end: fuel for reanimation, delve, threshold, or a graveyard payoff, with an empty library treated as the loss you sprint to avoid. This enchantment turns that fear into the win condition. Grind your library down to zero over successive upkeeps and the trigger fires in reverse, exiling the enchantment and dropping five graveyard cards back on top in an order you choose. What you actually buy for two mana is a scripted top-five: a guarantee that your next several draws are the exact cards you buried, whether that means recurring threats, stacking the pieces of a combo, or salvaging a deck you deliberately dumped. The self-exile is the governor on the whole thing; because the enchantment leaves once it resolves, you get one authored draw sequence rather than a recurring dredge engine, so the payoff stays a setup and never a loop. Three cards per upkeep is a slow clock in both directions, and that pace is the real cost: every trigger digs your own grave before it hands you the shovel, so you have to survive the turns it takes to empty out. Reading "mill" on an enchantment pointed at your own library looks like a contradiction until the second clause resolves and the graveyard becomes a staging ground; the friction of grinding to empty is the price for a draw order you get to write yourself.
