Infectious Growth
A sickness has invaded this world. It’s spreading, consuming every living thing, leaving infected husks where once the spark of life dwelt. The carriers, now an army of relentless, mindless, tireless hosts, is coming this way, and hope flees from their path.
Infectious Growth uses spells to pump up creatures with the Infect mechanic and deal lethal with poison counters.
A versatile Black-Green midrange deck that combines efficient threats with interaction, scaling into powerful late-game options.
