By utilizing Doc Aurlock, Grizzled Genius to slash the cost of spells cast from exile or the graveyard, Squee, the Immortal becomes an infinitely repeatable casting engine from your graveyard for a mere two red mana. Earthcraft turns Squee into a functional mana producer by letting his arrival untap a basic Mountain every time he enters, while Skirk Prospector provides the necessary sacrifice outlet to fuel the loop and generate the initial red mana. Together, this clever arrangement transforms Squee into a perpetual motion machine of sacrifices and re-casts, yielding an endless cascade of death triggers, enters-the-battlefield effects, and storm count.
