Poison Synergy

Cards that build the poison clock beyond plain infect or toxic creatures: proliferate engines like Atraxa, Praetors' Voice and Inexorable Tide that stack additional poison counters on opponents already poisoned, lords like Hand of the Praetors that buff infect creatures and add counters on cast, and payoffs like Phyresis Outbreak and Vraska, Betrayal's Sting that scale with how many poison counters opponents already have. Viral Drake combines infect with a proliferate activation. Distinct from poison.corrupted, which only flags the Corrupted threshold keyword itself; this entry covers the broader web of enablers, proliferators, and scaling payoffs that feed and exploit the ten-counter alternate-loss clock.
