This clever loop uses Revolutionist as the centerpiece, utilizing its enters-the-battlefield ability to continually fish Undying Malice back out of your graveyard whenever the spell is needed. By applying Undying Malice to Revolutionist ahead of time, sacrificing the creature to Phyrexian Altar immediately triggers its return with a +1/+1 counter while simultaneously generating the black mana required to cast the spell all over again. Because Phyrexian Altar lets you sacrifice the creature and Revolutionist effortlessly recycles your spells, you can repeat this cycle infinitely to generate endless sacrifice triggers, enters-the-battlefield effects, and storm count.
