This loop turns a simple +1/+1 counter into a devastating feedback engine by chaining Benthic Biomancer's looting ability directly into Heliod, Sun-Crowned's life-gain trigger. As you discard cards to Benthic Biomancer, Magmakin Artillerist fires off damage to each opponent, which in turn fuels Heliod, Sun-Crowned to place another +1/+1 counter right back onto Benthic Biomancer to restart the cycle. Meanwhile, Magmakin Artillerist can even cycle itself to kick things off or push through extra damage, creating an unstoppable loop of draws, discards, and direct life-draining pressure.
