By turning your creatures into a makeshift mana-reduction engine to help pay for Explosive Singularity, you can point a massive ten-damage blast directly at a creature while Phyresis quietly transforms all of that raw damage into lethal poison counters. Because Imodane, the Pyrohammer looks for a single-target instant or sorcery dealing damage to a creature, her ability naturally bridges the gap, translating that massive ten-damage hit into an identical wave of damage dealt to each opponent. With Phyresis granting infect to that triggered damage, your opponents are instantly overwhelmed with ten poison counters each, ending the game on the spot through state-based actions.
